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

753b1e486b Eliminate remaining uses of g_connman in Dash-specific code. (#1635)
This monstrous change eliminates all remaining uses of
g_connman global variable in Dash-specific code.

Unlike previous changes eliminating g_connman use
that were isolated to particular modules, this one covers
multiple modules simultaneously because they are so interdependent
that change in one module was quickly spreading to others.

This is mostly invariant change that was done by
* changing all functions using g_connman to use connman argument,
* changing all functions calling these functions to use connman argument,
* repeating previous step until there's nothing to change.

After multiple iterations, this process converged to final result,
producing code that is mostly equivalent to original one, but passing
CConnman instance through arguments instead of global variable.

The only exception to equivalence of resulting code is that I had to
create overload of CMasternodeMan::CheckAndRemove() method without arguments
that does nothing just for use in CFlatDB<CMasternodeMan>::Dump() and
CFlatDB<CMasternodeMan>::Load() methods.
Normal CMasternodeMan::CheckAndRemove() overload now has argument of
CConnman& type and is used everywhere else.

The normal overload has this code in the beginning:

    if(!masternodeSync.IsMasternodeListSynced()) return;

Masternode list is not synced yet when we load "mncache.dat" file,
and we save "mncache.dat" file on shutdown, so I presume that it's OK
to use overload that does nothing in both cases.

- Don't allow assert to have side-effects

8b5f47e686 Masternode classes: Remove repeated/un-needed code and data (#1572)
* Remove un-needed #includes (what is the policy?)

Data was duplicated in masternode_info_t and CMasternode classes:

* CMasternode is changed to inherit from masternode_info_t
  so the data members are inherited rather than repeated
 (also inherits unrepeated nTimeLastPing and fInfoValid members;
  this slight intrusiveness made up for in simplicity).

* Use in-class member initializers (C++11) for defaults,
  so only non-default initializers are required in the lists.
  Allows to shorten repetitous constructor initializer lists.
  This makes checking for uninitialized data simpler.

* Default constructors are defined as "= default;" if possible.

* masternode_info_t is changed to behave like an aggregate
 (but requires over-complicated constructors until c++14).
  There are pros and cons here - aggregate initialization
  is convenient but implicit).

* Removed user-defined swap functions.
  They appear to only be used in operator= definitions,
  using the copy-in,swap-and-return idiom:

* Default operator=, where possible.

* Move in class `friend bool operator==` out-of-class.

105713c10a Sync overhaul (#1564)
* Change sync process:
- IsBlockchainSynced(): drop CheckNodeHeight() and all complicated code, use fInitialDownload in UpdatedBlockTip() to switch initial states
- ProcessTick(): detect sleep mode like it was in IsBlockchainSynced(), not by number of masternodes

* Changes for sync in governance:
- do not keep sync alive on ConfirmInventoryRequest()
- skip some governance actions until we are synced to some level

* do not run CMasternodeMan::UpdateLastPaid() until winners list is synced

* start syncing mn list on the same node right after requesting sporks

* replace nTimeLast<Asset> with the unified nTimeLastBumped, bump on UpdatedBlockTip

* fix comments and LogPrintf-s

* remove excessive MASTERNODE_SYNC_IBD

* a bit more descriptive BumpAssetLastTime in few cases

a9d771e497 Backport Bitcoin PR#8085: p2p: Begin encapsulation (#1537)
* net: move CBanDB and CAddrDB out of net.h/cpp

This will eventually solve a circular dependency

* net: Create CConnman to encapsulate p2p connections

* net: Move socket binding into CConnman

* net: move OpenNetworkConnection into CConnman

* net: move ban and addrman functions into CConnman

* net: Add oneshot functions to CConnman

* net: move added node functions to CConnman

* net: Add most functions needed for vNodes to CConnman

* net: handle nodesignals in CConnman

* net: Pass CConnection to wallet rather than using the global

* net: Add rpc error for missing/disabled p2p functionality

* net: Pass CConnman around as needed

* gui: add NodeID to the peer table

* net: create generic functor accessors and move vNodes to CConnman

* net: move whitelist functions into CConnman

* 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

* net: move vNodesDisconnected into CConnman

* Made the ForEachNode* functions in src/net.cpp more pragmatic and self documenting

* Convert ForEachNode* functions to take a templated function argument rather than a std::function to eliminate std::function overhead

* net: move MAX_FEELER_CONNECTIONS into connman
