0c85dc30e6b628f7538a67776c7eefcb84ef4f82 p2p: Don't use timestamps from inbound peers (Martin Zumsande)
Pull request description:
`GetAdjustedTime()` (used e.g. in validation and addrman) returns a time with an offset that is influenced by timestamps that our peers have sent us in their version message.
Currently, timestamps from all peers are used for this.
However, I think that it would make sense to ignore the timedata samples from inbound peers, making it much harder for others to influence the Adjusted Time in a targeted way.
With the extra feeler connections (every 2 minutes on average) and extra block-relay-only connections (every 5 minutes on average) there are also now plenty of opportunities to gather a meaningful number of timedata samples from outbound peers.
There are some measures in place to prevent abuse: the `-maxtimeadjustment` parameter with a default of 70 minutes, warnings in cases of large deviations, only using the first 200 samples ([explanation](383d350bd5/src/timedata.cpp (L57-L72))), but I think that only using samples from outbound connections in the first place would be an additional safety measure that would make sense.
See also issue #4521 for further context and links: There have been several discussions in the past about replacing or abolishing the existing timedata system.

A negative chain height is only used to denote an empty chain, not the height of any block.
So stop testing that and remove a suppression.

## Additional Information
* This pull request's primary purpose is to restore `LogPrintLevel`s from backports in [dash#6333](https://github.com/dashpay/dash/pull/6333) that were changed to `LogPrint`s as they were backported before `LogPrintLevel` was backported.
* ~~`clang-format` suggestions for `LogPrintLevel` have to be ignored in order to prevent the linter from tripping due to a "missing newline" ([build](https://gitlab.com/dashpay/dash/-/jobs/8398818860#L54)).~~ Resolved by applying diff ([source](https://github.com/dashpay/dash/pull/6399#issuecomment-2488992710)).
* `SharedLock` was introduced in [dash#5961](https://github.com/dashpay/dash/pull/5961) and `PrintLockContention` was removed in [dash#6046](https://github.com/dashpay/dash/pull/6046) but the changes in the latter were not extended to the former. This has been corrected as part of this pull request.
## Breaking Changes
None expected.

dafa7363a3 fix: respect SENDDSQUEUE message, move DSQ relay into net processing / peerman (pasta)
Pull request description:
## Issue being fixed or feature implemented
in #6148, I broke the functionality where a peer must opt in / opt out of DSQUEUE messages. This was mostly ok, and not immediately detected, as with this bug, simply everyone would receive DSQ messages over inventory (or classically, old proto versions were not affected by this bug). But this still would result in quite a bit of wasted bandwidth for peers which may not care about DSQ at all.
## What was done?
This commit should restore the prior functionality, where a node should send the SENDDSQUEUE message if they wish to receive DSQs. Once they've sent that, depending on their protocol version, they will either have the messages pushed to them as available, or on modern protocols, they will thereafter receive DSQs over the inventory system.
NOTE: I also refactor the code in this commit, moving some network proccessing into.... wait for it... net_processing.cpp! This allowed us to remove some dependencies in coinjoin.h. DSQ messages are now relayed to peers by calling peer_manager.RelayDSQ
## How Has This Been Tested?
I have not yet mixed on testnet with this; we should include it in rc.2 and test
## Breaking Changes
Slightly breaking for v22.0.x (so rc.1), as they in theory could be relying on this new logic of always receiving the DSQ inv. But I don't think anyone besides core is using this new protocol.

Follow-up to 42e1b5d979 (#12486).
- update call to `round()` with our utility function `satoshi_round()` to avoid intermittent test failures
- rename `fee_per_kB` to `feerate_BTC_kvB` for precision
- store division result in `feerate_BTC_vB`
Possibly resolves#19418.

Pull request description:
## Issue being fixed or feature implemented
High m_nodes_mutex lock contention during high load
## What was done?
this commit should have a few benefits:
1. previous logic using ForEachNode results in locking m_nodes_mutex, a highly contended RecursiveMutex, AND m_peer_mutex(in GetPeerRef)
2. prior also resulted in calling .find over the m_peer_map for each node. Basically old logic was (probably) O(n(nlogn) the new logic results in acquiring m_peer_mutex once and looping over the list of peers, (probably) O(n)
3. Moves networking logic out of llmq/ and into actual net_processing.cpp
## How Has This Been Tested?
Hasn't really yet; it builds, but I need to run tests / maybe deploy to testnet mn

Currently we use the raw helper, but that means that timeout scaling isn't applying.. I think this may be a cause of a lot of the functional test failures that we see in tsan / ubsan.

**This does change the logic!** We no longer prioritize asking MNs. This is probably fine? I don't specifically recall why we wanted to ask MNs besides potentially that they may be higher performing or better connected? We can potentially restore this logic once we bring masternode connection logic into Peer
Does also change logic, by short-circuiting once peersToAsk is full.
This commit has the added benefit of reducing contention on m_nodes_mutex due to no-longer calling connman.ForEachNode not once but twice
This may slightly increase contention on m_peer_mutex; but that should be an ok tradeoff for not only removing dependencies, but also reducing contention on a much more contested RecursiveMutex
3d67771f89 refactor: add in quorumBaseBlockIndexCache to reduce cs_main contention (pasta)
Pull request description:
## Issue being fixed or feature implemented
subset of https://github.com/dashpay/dash/pull/6418; only includes the new quorumBaseBlockIndexCache, doesn't include the caching of the chain-tip, as that introduced regressions I'm still debugging.
## What was done?
introduce a LRU cache for quorumHash -> const CBlockIndex*; this should significantly reduce cs_main contention during high transaction load.
## How Has This Been Tested?
Ran tests locally; let's see CI happy, and I also intend to run this on a testnet MN first and see the level of contention reduction

None
