We now have hundreds of MN connections due to the new intra quorum connections,
which means having a limiting semaphore here doesn't make sense anymore. It
actually causes DKG and signing failures as not all necessary connections
can be established.
Masternode connections are still implicitely limited as there is always
only a limited set of LLMQs active.
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).

Only sleep 100ms when we previously tried to connect a MN. The back-off
logic in ThreadOpenMasternodeConnections will prevent too many unsuccessful
connects to offline/bad nodes.
Instead of only doing it the first time. This is a preparation for
the new intra-quorum connection system (which connects all members to all
other members)
The way it was implemented caused vPendingMasternodes entries to be popped
but not necessarily connected to when at the same time quorum connections
were pending.

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.

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.

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.

660f5f1 net: don't retry failed oneshot connections forever (Cory Fields)
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.

fb6f6b1 bluematt's testnet-seed now supports x9 (and is just a static list) (Matt Corallo)
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.

While reviewing the safeguards against deliberate node isolation on the network by malicious actors, I found a good de-duplication candidate.
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.

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.
