fe8c18ca77 Merge #10574: Remove includes in .cpp files for things the corresponding .h file already included
a720b92 Remove includes in .cpp files for things the corresponding .h file already included (practicalswift)

Pull request description:

  Remove includes in .cpp files for things the corresponding .h file already included.

  Example case:
  * `addrdb.cpp` includes `addrdb.h` and `fs.h`
  * `addrdb.h` includes `fs.h`

  Then remove the direct inclusion of `fs.h` in `addrman.cpp` and rely on the indirect inclusion of `fs.h` via the included `addrdb.h`.

  In line with the header include guideline (see #10575).

Pull request description:

  Use `std::unique_ptr` (C++11) where possible.

  Rationale:
  1. Avoid resource leaks (specifically: forgetting to `delete` an object created using `new`)
  2. Avoid undefined behaviour (specifically: double `delete`:s)

  **Note to reviewers:** Please let me know if I've missed any obvious `std::unique_ptr` candidates. Hopefully this PR should cover all the trivial cases.

Fix node protection logic false positives (#3314)
We could be reading multiple messages from a socket buffer at once _without actually processing them yet_ which means that `fSuccessfullyConnected` might not be switched to `true` at the time we already parsed `VERACK` message and started to parse the next one. This is basically a false positive and we drop a legit node as a result even though the order of messages sent by this node was completely fine. To fix this I partially reverted #2790 (where the issue was initially introduced) and moved the logic for tracking the first message into ProcessMessage instead.

2c084a6 net: Minor accumulated cleanups (Thomas Snider)

Pull request description:

  From now-derelict larger changes I had been working on, here are a series of DRY refactors/cleanups.  Net loss of 35 lines of code - a small step in the good fight.

  In particular I think operator!= should only ever be implemented as a negation of operator==.  Lower chance for errors, and removes the possibility of divergent behavior.

Pull request description:

  A risk exists where a malicious DNS seeder eclipses a node by returning an enormous number of IP addresses. In this commit we mitigate this risk by limiting the number of IP addresses addrman learns to 256 per DNS seeder.

Pull request description:

  As introduced by (my suggestion, sorry, in) #11512, failed dns resolves end up as oneshots. But failed oneshots are re-added as oneshots, so we need to make sure that we're not queuing these up forever after failed resolves.

  Rather than trying to differentiate, I think we should just not re-add failed oneshots and be done with it.

  Maybe @sipa can shed a light on what the original intention was.

Pull request description:

  4440710 broke inserting entries into addrman from dnsseeds which
  did not support service bits, as well as static seeds. Static seeds
  were already being filtered by UA for 0.13.1+ (ie NODE_WITNESS), so
  simply changing the default service bits to include NODE_WITNESS
  (and updating docs appropriately) is sufficient. For DNS Seeds, not
  supporting NODE_WITNESS is no longer useful, so instead use
  non-filtering seeds as oneshot hosts irrespective of named proxy.

  I've set my testnet-seed to also support x9, though because it is simply a static host, it may be useful to leave the support off so that it is used as a oneshot to get addresses from a live node instead. I'm fine with either.

  I think this form is much more legible (the type of `cutoffs` notwithstanding).  ReverseCompareNodeTimeConnected is not included in the list since the cutoff size is a function of the remaining number of nodes in the candidate eviction set.

2416dd7 net: separate resolving and conecting (Cory Fields)

Pull request description:

  This is a greatly simplified version of #10285, which only aims to address async resolving.

  It essentially breaks up two wrapper functions for things only used in one place (ConnectSocketDirectly/ConnectThroughProxy) in favor of calling them directly. This allows us to fully handle resolves before attempting a connection, as is necessary for async connections.

  As a bonus, I believe the logic is now much easier to follow than before.

36d326e8b Use nullptr instead of zero (0) as the null pointer constant (practicalswift)

Pull request description:

  Use `nullptr` instead of zero (0) as the null pointer constant.

  The road towards `nullptr` (C++11) is split into two PRs:
  * `NULL` → `nullptr` is handled in PR #10483 (scripted)
  * `0` → `nullptr` is handled in PR #10645 (manual, this PR)

  By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.

  For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &
  Stroustrup), http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf

be127bc2ee Replace vecAskFor with a priority queue (#3147)
This avoids sorting before looping through it to figure out what to
request. The assumption that sorting would be cheap when vecAskFor is
already mostly sorted (only unsorted at the end) turned out to be false.
In reality, ~50% of CPU time was consumed by the sort when a lot of traffic
(thousands of TXs) happen.

Pull request description:

  This is an alternative approach to #11534.  Rather than disconnect an outbound peer when our tip looks stale, instead try to connect to an additional outbound peer.

  Periodically, check to see if we have more outbound peers than we target (ie if any extra peers are in use), and if so, disconnect the one that least recently announced a new block (breaking ties by choosing the newest peer that we connected to).

44407100f Replace relevant services logic with a function suite. (Matt Corallo)

Pull request description:

  This was mostly written as a way to clean things up so that the NETWORK_LIMITED PR (#10387) can be simplified a ton, but its also a nice standalone cleanup that will also require a bit of review because it tweaks a lot of stuff across net. The new functions are fine in protocol.h right now since they're straight-forward, but after NETWORK_LIMITED will really want to move elsewhere after @theuni moves the nServices-based selection to addrman from connman.

  Adds HasAllRelevantServices and GetRelevantServices, which check
  for NETWORK|WITNESS.

  This changes the following:
   * Removes nRelevantServices from CConnman, disconnecting it a bit
     more from protocol-level logic.
   * Replaces our sometimes-connect-to-!WITNESS-nodes logic with
     simply always requiring WITNESS|NETWORK for outbound non-feeler
     connections (feelers still only require NETWORK).
   * This has the added benefit of removing nServicesExpected from
     CNode - instead letting net_processing's VERSION message
     handling simply check HasAllRelevantServices.
   * This implies we believe WITNESS nodes to continue to be a
     significant majority of nodes on the network, but also because
     we cannot sync properly from !WITNESS nodes, it is strange to
     continue using our valuable outbound slots on them.
   * In order to prevent this change from preventing connection to
     -connect= nodes which have !WITNESS, -connect nodes are now
     given the "addnode" flag. This also allows outbound connections
     to !NODE_NETWORK nodes for -connect nodes (which was already true
     of addnodes).
   * Has the (somewhat unintended) consequence of changing one of the
     eviction metrics from the same
     sometimes-connect-to-!WITNESS-nodes metric to requiring
     HasRelevantServices.

  This should make NODE_NETWORK_LIMITED much simpler to implement.

  ```

  The read of the uninitialized variable `nLocalServices` is triggered by `g_connman->GetLocalServices()` in `getnetworkinfo(const JSONRPCRequest& request)` (`net.cpp:462`):

  ```c++
  UniValue getnetworkinfo(const JSONRPCRequest& request)
  {
  ...
      if(g_connman)
          obj.push_back(Pair("localservices", strprintf("%016x", g_connman->GetLocalServices())));
  ...
  }
  ```

  The reason for the uninitialized `nLocalServices` is that `CConnman::Start(...)` is not called
  by the tests, and hence the initialization normally performed by `CConnman::Start(...)` is
  not done.

  This commit adds a method `Init(const Options& connOptions)` which is called by both the
  constructor and `CConnman::Start(...)`. This method initializes `nLocalServices` and the other
  relevant values from the supplied `Options` object.

Pull request description:

  Rationale:

  Readability, SetSocketNonBlocking does what it says on the tin.

  Consistency, More consistent with the rest of the API in this unit.

  Reusability, SetSocketNonBlocking can also be used by clients that may not want to close the socket on failure.

  This also moves the responsibility of closing the socket back to the caller that opened it, which in general should know better how and when to close it.

2f21e55514 Remove legacy InstantSend code (#3020)
* Remove ppszTypeName from protocol.cpp and reimplement GetCommand

This removes the need to carefully maintain ppszTypeName, which required
correct order and also did not allow to permanently remove old message
types.

To get the command name for an INV type, GetCommandInternal uses a switch
which needs to be maintained from now on.

The way this is implemented also resembles the way it is implemented in
Bitcoin today, but it's not identical. The original PR that introduced the
switch case in Bitcoin was part of the Segwit changes and thus never got
backported. I decided to implement it in a slightly different way that
avoids throwing exceptions when an unknown INV type is encountered.

IsKnownType will now also leverage GetCommandInternal() to figure out if
the INV type is known locally. This has the side effect of old/legacy
message types to return false from now on. We will depend on this side
effect in later commits when we remove legacy InstantSend code.

* Stop handling/relaying legacy IX messages

When we receive an IX message, we simply treat it as a regular TX and relay
it as such.

We'll however still request IX messages when they are announced to us. We
can't simply revert to requesting TX messages in this case as it might
result in the other peer not answering due to the TX not being in mapRelay
yet. We should at some point in the future completely drop handling of IX
messages instead.

* Remove IsNewInstantSendEnabled() and only use IsInstantSendEnabled()

* Remove legacy InstantSend from GUI

* Remove InstantSend from Bitcoin/Dash URIs

* Remove legacy InstantSend from RPC commands

* Remove legacy InstantSend from wallet

* Remove legacy instantsend.h include

* Remove legacy InstantSend from validation code

* Completely remove remaining legacy InstantSend code

* Remove now unused spork

* Fix InstantSend related test failures

* Remove now obsolete auto IS tests

* Make spork2 and spork3 disabled by default

This should have no influence on mainnet as these sporks are actually set
there. This will however affect regtest, which shouldn't have LLMQ based
InstantSend enabled by default.

* Remove instantsend tests from dip3-deterministicmns.py

These were only testing legacy InstantSend

* Fix .QCheckBox#checkUsePrivateSend styling a bit

* s/TXLEGACYLOCKREQUEST/LEGACYTXLOCKREQUEST/

* Revert "verified via InstantSend" back to "verified via LLMQ based InstantSend"

* Use cmd == nullptr instead of !cmd

* Remove last parameter from AvailableCoins call

This was for fUseInstantSend which is not present anymore since rebase

241f76f9bf Collection of minor performance optimizations (#2855)
* Merge #13176: Improve CRollingBloomFilter performance: replace modulus with FastMod

9aac9f90d5e56752cc6cbfac48063ad29a01143c replace modulus with FastMod (Martin Ankerl)

Pull request description:

  Not sure if this is optimization is necessary, but anyway I have some spare time so here it is. This replaces the slow modulo operation with a much faster 64bit multiplication & shift. This works when the hash is uniformly distributed between 0 and 2^32-1. This speeds up the benchmark by a factor of about 1.3:

  ```
  RollingBloom, 5, 1500000, 3.73733, 4.97569e-07, 4.99002e-07, 4.98372e-07 # before
  RollingBloom, 5, 1500000, 2.86842, 3.81630e-07, 3.83730e-07, 3.82473e-07 # FastMod
  ```

  Be aware that this changes the internal data of the filter, so this should probably
  not be used for CBloomFilter because of interoperability problems.

* Use unordered_map in CSporkManager

In one of my profiling sessions with many InstantSend transactions
happening, calls into CSporkManager added up to about 1% of total CPU time.
This is easily avoidable by using unordered maps.

* Use std::unordered_map instead of std::map in limitedmap

* Use unordered_set for CNode::setAskFor

* Add serialization support for unordered maps and sets

* Use unordered_map for mapArgs and mapMultiArgs

* Let limitedmap prune in batches and use unordered_multimap

Due to the batched pruning, there is no need to maintain an ordered map
of values anymore. Only when nPruneAfterSize, there is a need to create
a temporary ordered vector of values to figure out what can be removed.

* Instead of using a multimap for mapAskFor, use a vector which we sort on demand

CNode::AskFor will now push entries into an initially unordered vector
instead of an ordered multimap. Only when we later want to use vecAskFor in
SendMessages, we sort the vector.

The vector will actually be mostly sorted in most cases as insertion order
usually mimics the desired ordering. Only the last few entries might need
some shuffling around. Doing the sort on-demand should be less wasteful
then trying to maintain correct order all the time.

* Fix compilation of tests

* Fix limitedmap tests

* Rename limitedmap to unordered_limitedmap to ensure backports conflict

This ensures that future backports that depends on limitedmap's ordering
conflict so that we are made aware of needed action.

* Fix compilation error on Travis

* Keep track of proRegTxHash in CConnman::masternodeQuorumNodes map

* Fix serialization of std::tuple with const rvalue elements

Having serialization and deserialization in the same specialized template
results in compilation failures due to the "if(for_read)" branch.

* Implement MNAUTH message

This allows masternodes to authenticate themself.

* Protect fresh incoming connections for a second from eviction

Give fresh connections some time to do the VERSION/VERACK handshake and
an optional MNAUTH when it's a masternode. When an MNAUTH happened, the
incoming connection is then forever protected against eviction.

If a timeout of 1 second occurs or the first message after VERACK is not
MNAUTH, the node is not protected anymore and becomes eligable for
eviction.

* Avoid connecting to masternodes if an incoming connection is from the same one

Now that incoming connections from MNs authenticate them self, we can avoid
connecting to the same MNs through intra-quorum connections.

This is useful when many messages need are pushed with optimistic send being
disabled. After all messages have been pushed, WakeSelect() can then wakeup
the select() thread and force a re-check for pending data to send.

This is currently only implemented for POSIX compliant systems as we assume
that heavy-load daemons (like masternodes) are usually run on Linux.

cf29320988 Allow to disable optimistic send in PushMessage()
Profiling has shown that optimistic send causes measurable slowdowns when
many messages are pushed, even if the sockets are non-blocking. Better to
allow disabling of optimistic sending in such cases and let the network
thread do the actual socket calls.

b5142ee2ce Implement RemoveAskFor to indicate that we're not interested in an item anymore (#2384)
* Implement RemoveAskFor to indicate that we're not interested in an item anymore

When an INV item is received from the first node, the item is requested
immediately. If the same item is received from another node, an entry is
added to mapAskFor which marks the item for re-requesting in case the first
node did not respond. When the item is received from the first node,
the item was previously never removed from mapAskFor. Only the later getdata
loop in SendMessages would then gradually remove items from the map. This
is quite delayed however as the entries in mapAskFor have a timeout value.

RemoveAskFor allows to remove all entries from mapAskFor and setAskFor
when we are not interested in the item anymore (e.g. because we received
it already).

* Call RemoveAskFor whenever we receive a message

* Only pass hash instead of CInv object to RemoveAskFor

A pack of small fixes (#1992)
* Make sure gobject collateral was mined

`CGovernanceObject::IsCollateralValid()` would still fail for non-mined collateral later trying to check confirmations

* Fix powLimit for mainnet/testnet

That's a legacy thing, slightly rising it to match the actual bit-shifted value has no effect because real values are already lower.
Also clarify values for all networks in comments.

* Check for script addresses in CSuperblock::ParsePaymentSchedule()

Sentinel should already be downvoting such triggers if they would exist, no need to store/relay them.

* Do not process already known valid vote twice in CGovernanceObject::ProcessVote()

This should be handled by `CGovernanceManager::ProcessVote()` but imo it's better to have this at the `CGovernanceObject::ProcessVote()` level as well.

* Make sure CGovernanceObjectVoteFile::AddVote() never adds/updates already known votes

The way `CGovernanceObjectVoteFile::AddVote()` is used (i.e. wrapped in `CGovernanceObjectVoteFile::HasVote()` condition) it's already the case. Hoever nothing would guarantee consistency if it would be used elsewhere without such wrapper, so it's better to have similar check inside.

* Do not even try mnb recovery when -connect is set

`CConnman::ThreadOpenMasternodeConnections()` thread won't even start when `-connect` is set, so no need to ask for recovery, there is nothing that is going to be able to process such request.

* No need for SIGHASH_ANYONECANPAY in PS collateral signature

Collateral is just a normal tx created and signed by each participant individually, there is no need for special sig types.

* Release semMasternodeOutbound in CConnman::Interrupt()

Re-align Dash code with Bitcoin.

532b9fa3db Use OpenNetworkConnection instead of calling ConnectNode directly in Dash code (#1857)
ConnectNode is meant to be private and should not be leaked outside of
CConnman. This leaking resulted in multiple problems with AddRef/Release
behaviour. We use OpenNetworkConnectio/OpenMasternodeConnection from now on
and use appropriate ForNode calls to access the CNode* instance.

This commit also changes the behaviour for already connected nodes which
are afterwards requested for a masternode connection. We don't set
fMasternode=true anymore on such nodes, which means it won't be auto
disconnected anymore from ProcessMasternodeConnections.

cd9c6994c2 Implement named devnets (#1791)
* Initial devnet

* Move genesis block adding into its own method

* Introduce -allowprivatenet to lift limitation on RFC1918 addresses

Normally, RFC1918 (192.168.x.x/10.x.x.x/...) addresses are not allowed
to be relayed. Also, masternodes won't start when the address is considered
invalid.

This is needed to test local devnet or regtest based networks.

* Lift the requirement of minimum MN age for regtest/devnet

* Implement named devnets

This allows the creation of multiple independent devnets. Each one is
identified by a name which is hardened into a "devnet genesis" block,
which is automatically positioned at height 1. Validation rules will
ensure that a node from devnet=test1 never be able to accept blocks
from devnet=test2. This is done by checking the expected devnet genesis
block.

The genesis block of the devnet is the same as the one from regtest. This
starts the devnet with a very low difficulty, allowing us to fill up
needed balances for masternodes very fast.

Also, the devnet name is put into the sub-version of the VERSION message.
If a node connects to the wrong network, it will immediately be disconnected.

* Allow to select multiple addresses from the same group in devnet/regtest

The selection code normally only allows to select addresses from the same
group (e.g. 192.168.x.x) once. This results in connecting to only a single
node in devnet/regtest.

* Show the devnet name in the title bar and on the loading screen

* Add AllowMultipleAddressesFromGroup to chainparams and use it in net.cpp

* Remove unused/unneeded scripts from devnet geneses creation

1. OP_RETURN not needed in input script of devnet genesis
2. genesisOutputScript was unused

* Fix copy/paste error in -allowprivatenet description

* Improve -devnet parameter error handling

- Only allow one of -devnet, -regtest or -testnet
- Only allow -devnet=name to be specified once

* Use different datadir for each devnet

* Fix `devnet-devnet` issue

* Fix devnet splashscreen (should use testnet img)

* Avoid passing devNetName around (most of the time)

* Remove nMaxTipAge from CDevNetParams

* net: require lookup functions to specify all arguments

To make it clear where DNS resolves are happening

* net: manually resolve dns seed sources

Note: Some seeds aren't actually returning an IP for their name entries, so
they're being added to addrman with a source of [::].

This commit shouldn't change that behavior, for better or worse.

* net: resolve outside of storage structures

Rather than allowing CNetAddr/CService/CSubNet to launch DNS queries, require
that addresses are already resolved.

This greatly simplifies async resolve logic, and makes it harder to
accidentally leak DNS queries.

c56ba56e79 net: Consistently use GetTimeMicros() for inactivity checks (#1588)
The use of mocktime in test logic means that comparisons between
GetTime() and GetTimeMicros()/1000000 are unreliable since the former
can use mocktime values while the latter always gets the system clock;
this changes the networking code's inactivity checks to consistently
use the system clock for inactivity comparisons.

Also remove some hacks from setmocktime() that are no longer needed,
now that we're using the system clock for nLastSend and nLastRecv.

2472999da0 Backport Bitcoin PR#9441: Net: Massive speedup. Net locks overhaul (#1586)
* net: fix typo causing the wrong receive buffer size

Surprisingly this hasn't been causing me any issues while testing, probably
because it requires lots of large blocks to be flying around.

Send/Recv corks need tests!

* net: make vRecvMsg a list so that we can use splice()

* net: make GetReceiveFloodSize public

This will be needed so that the message processor can cork incoming messages

* net: only disconnect if fDisconnect has been set

These conditions are problematic to check without locking, and we shouldn't be
relying on the refcount to disconnect.

* net: wait until the node is destroyed to delete its recv buffer

when vRecvMsg becomes a private buffer, it won't make sense to allow other
threads to mess with it anymore.

* net: set message deserialization version when it's actually time to deserialize

We'll soon no longer have access to vRecvMsg, and this is more intuitive anyway.

* net: handle message accounting in ReceiveMsgBytes

This allows locking to be pushed down to only where it's needed

Also reuse the current time rather than checking multiple times.

* net: record bytes written before notifying the message processor

* net: Add a simple function for waking the message handler

This may be used publicly in the future

* net: remove useless comments

* net: remove redundant max sendbuffer size check

This is left-over from before there was proper accounting. Hitting 2x the
sendbuffer size should not be possible.

* net: rework the way that the messagehandler sleeps

In order to sleep accurately, the message handler needs to know if _any_ node
has more processing that it should do before the entire thread sleeps.

Rather than returning a value that represents whether ProcessMessages
encountered a message that should trigger a disconnnect, interpret the return
value as whether or not that node has more work to do.

Also, use a global fProcessWake value that can be set by other threads,
which takes precedence (for one cycle) over the messagehandler's decision.

Note that the previous behavior was to only process one message per loop
(except in the case of a bad checksum or invalid header). That was changed in
PR #3180.

The only change here in that regard is that the current node now falls to the
back of the processing queue for the bad checksum/invalid header cases.

* net: add a new message queue for the message processor

This separates the storage of messages from the net and queued messages for
processing, allowing the locks to be split.

* net: add a flag to indicate when a node's process queue is full

Messages are dumped very quickly from the socket handler to the processor, so
it's the depth of the processing queue that's interesting.

The socket handler checks the process queue's size during the brief message
hand-off and pauses if necessary, and the processor possibly unpauses each time
a message is popped off of its queue.

* net: add a flag to indicate when a node's send buffer is full

Similar to the recv flag, but this one indicates whether or not the net's send
buffer is full.

The socket handler checks the send queue when a new message is added and pauses
if necessary, and possibly unpauses after each message is drained from its buffer.

* net: remove cs_vRecvMsg

vRecvMsg is now only touched by the socket handler thread.

The accounting vars (nRecvBytes/nLastRecv/mapRecvBytesPerMsgCmd) are also
only used by the socket handler thread, with the exception of queries from
rpc/gui. These accesses are not threadsafe, but they never were. This needs to
be addressed separately.

b9c67258ba Backport Bitcoin PR#9609: net: fix remaining net assertions (#1575) + Dashify
* Dont deserialize nVersion into CNode, should fix #9212

* net: deserialize the entire version message locally

This avoids having some vars set if the version negotiation fails.

Also copy it all into CNode at the same site. nVersion and
fSuccessfullyConnected are set last, as they are the gates for the other vars.
Make them atomic for that reason.

* net: don't run callbacks on nodes that haven't completed the version handshake

Since ForEach* are can be used to send messages to  all nodes, the caller may
end up sending a message before the version handshake is complete. To limit
this, filter out these nodes. While we're at it, may as well filter out
disconnected nodes as well.

Delete unused methods rather than updating them.

* net: Disallow sending messages until the version handshake is complete

This is a change in behavior, though it's much more sane now than before.

* net: log an error rather than asserting if send version is misused

Also cleaned up the comments and moved from the header to the .cpp so that
logging headers aren't needed from net.h

* Implement conditions for ForEachNode() and ForNode() methods of CConnman.

A change making ForEachNode() and ForNode() methods ignore nodes that
have not completed initial handshake have been backported from Bitcoin.
Unfortunately, some Dash-specific code needs to iterate over all nodes.

This change introduces additional condition argument to these methods.
This argument is a functional object that should return true for nodes
that should be taken into account, not ignored.

Two functional objects are provided in CConnman namespace:
* FullyConnectedOnly returns true for nodes that have handshake completed,
* AllNodes returns true for all nodes.

Overloads for ForEachNode() and ForNode() methods without condition argument
are left for compatibility with non-Dash-specific code.
They use FullyConnectedOnly functional object for condition.

* Iterate over all nodes in Dash-specific code using AllNodes condition.

Use AllNodes functional object as newly introduced condition argument for
ForEachNode() and ForNode() methods of CConnman to iterate over all nodes
where needed in Dash-specific code.

cc4db34f4d net: only delete CConnman if it's been created (#1555)
In the case of (for example) an already-running bitcoind, the shutdown sequence
begins before CConnman has been created, leading to a null-pointer dereference
when g_connman->Stop() is called.

Instead, Just let the CConnman dtor take care of stopping.

b621cfb5fb Backport Bitcoin PR#8708: net: have CConnman handle message sending (#1553)
* serialization: teach serializers variadics

Also add a variadic CDataStream ctor for ease-of-use.

* connman is in charge of pushing messages

The changes here are dense and subtle, but hopefully all is more explicit
than before.

- CConnman is now in charge of sending data rather than the nodes themselves.
  This is necessary because many decisions need to be made with all nodes in
  mind, and a model that requires the nodes calling up to their manager quickly
  turns to spaghetti.

- The per-node-serializer (ssSend) has been replaced with a (quasi-)const
  send-version. Since the send version for serialization can only change once
  per connection, we now explicitly tag messages with INIT_PROTO_VERSION if
  they are sent before the handshake. With this done, there's no need to lock
  for access to nSendVersion.

  Also, a new stream is used for each message, so there's no need to lock
  during the serialization process.

- This takes care of accounting for optimistic sends, so the
  nOptimisticBytesWritten hack can be removed.

- -dropmessagestest and -fuzzmessagestest have not been preserved, as I suspect
  they haven't been used in years.

* net: switch all callers to connman for pushing messages

Drop all of the old stuff.

* drop the optimistic write counter hack

This is now handled properly in realtime.

* net: remove now-unused ssSend and Fuzz

* net: construct CNodeStates in place

* net: handle version push in InitializeNode

* net: move nLastNodeId to CConnman

* net: move nLocalHostNonce to CConnman

This behavior seems to have been quite racy and broken.

Move nLocalHostNonce into CNode, and check received nonces against all
non-fully-connected nodes. If there's a match, assume we've connected
to ourself.

* net: move messageHandlerCondition to CConnman

* net: move send/recv statistics to CConnman

* net: move SendBufferSize/ReceiveFloodSize to CConnman

* net: move nLocalServices/nRelevantServices to CConnman

These are in-turn passed to CNode at connection time. This allows us to offer
different services to different peers (or test the effects of doing so).

* net: move semOutbound and semMasternodeOutbound to CConnman

* net: SocketSendData returns written size

* net: move max/max-outbound to CConnman

* net: Pass best block known height into CConnman

CConnman then passes the current best height into CNode at creation time.

This way CConnman/CNode have no dependency on main for height, and the signals
only move in one direction.

This also helps to prevent identity leakage a tiny bit. Before this change, an
attacker could theoretically make 2 connections on different interfaces. They
would connect fully on one, and only establish the initial connection on the
other. Once they receive a new block, they would relay it to your first
connection, and immediately commence the version handshake on the second. Since
the new block height is reflected immediately, they could attempt to learn
whether the two connections were correlated.

This is, of course, incredibly unlikely to work due to the small timings
involved and receipt from other senders. But it doesn't hurt to lock-in
nBestHeight at the time of connection, rather than letting the remote choose
the time.

* net: pass CClientUIInterface into CConnman

* net: Drop StartNode/StopNode and use CConnman directly

* net: Introduce CConnection::Options to avoid passing so many params

* net: add nSendBufferMaxSize/nReceiveFloodSize to CConnection::Options

This reverts commit 1f828f45ec.

The commit being reverted changed FindNode(const CService& addr)
to make no difference between nodes with the same IP address,
but different ports, but only for regtest network.
As functional tests run several nodes on different ports or the same
IP address (127.0.0.1), this eventually started breaking functional tests.
The only use for regtest network I know is for functional tests,
so it's time to revert that commit.
