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).

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.

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.

* 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.

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

* Only relax default port check when AllowMultiplePorts is true

It's not a good idea to try to connect to an old address of a masternode.
This will also skip connection attempts when the masternode is not in the
valid set anymore (banned or collateral spent).
* Pass CNode* to IsMasternodeQuorumNode and let it also check verifiedProRegTxHash
This makes IsMasternodeQuorumNode return true on incoming peer connections
as well.
* Let GetMasternodeQuorumNodes also take verifiedProRegTxHash into account
This makes it return NodeIds for incoming peer connections as well.
* Remove AddParticipatingNode and the need for it
This was needed in the past when we were unable to identify incoming
connections from other quorum members. Now that we have MNAUTH, we can
easily identify all connected members.
* Don't track interestedIn quorums in CSigSharesNodeState anymore
Same as with the previous commit, we're now able to easily identify which
nodes to announce sig shares to.
* Remove unused CConnman::GetMasternodeQuorumAddresses
* Sort evo/* source files in Makefile.am
* Keep track of proRegTxHash in CConnman::masternodeQuorumNodes map
We will later need the proRegTxHash
* 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.
* Apply review suggestions
* Bump MAX_OUTBOUND_MASTERNODE_CONNECTIONS to 250 on masternodes
Masternodes now need to connect to much more other MNs due to the intra-quorum
communication.
250 is a very conservative value loosely based on the absolute worst-case
number of outgoing connections required, assuming that a MN manages to
become part of all 24 active LLMQs.
* Fix infinite loop in CConnman::Interrupt
* Move out conditional calc into it's own variable
