57fb0874ef feat: broadcast dsq messages using the inventory system (pasta)
Pull request description:
## Issue being fixed or feature implemented
DSQ messages are 142 bytes.
Previously, assuming a relatively highly connected masternode hosting 100 connection, each round of coinjoin will result in 14.2KB (100*142) of inbound and outbound traffic each.
## What was done?
Now, using the inventory system, a message will first use 36 bytes per peer (sending and receiving), plus the size of a `getdata` message and the actual message itself. As a result, bandwidth usage for 1 round of mixing would be closer to 36 * 100 + 142 (dsq) + 36 (getdata) = ~3.8KB, a reduction of around ~73%
## How Has This Been Tested?
Has not been; @UdjinM6 especially please review well :)
## Breaking Changes
Does introduce a new protocol version, but in a backwards compatible way. I don't think this would need to be delayed to v22 for any reason.

## Issue being fixed or feature implemented
V20 is activated on mainnet: time to bury it!
https://github.com/dashpay/dash/issues/6186
## What was done?
Hard-fork v20 is buried and it requires to implement multiple fixes, simplifications, refactoring:
- some tests for EHF moved from functional tests to unit tests
- fixed crash in Credit Pool if DIP3 is not activated yet
- added a requirement for v20 activation for `CMNHFManager::GetSignalsStage`
- removed useless code from functional test feature_llmq_rotation
- renamed variables "v20" to "mn_rr" in feature_llmq_evo.py so far as actually used fork is mn_rr
## How Has This Been Tested?
Some unit and functional tests to succeed.
Done reindex (just in case):

There's little sense in passing a ref to `ArgsManager` just to set a few
values because we'll be `const`-ing them in an upcoming commit.
Arguments supplied are expected to last the lifetime of the program's

Pull request description:
## Issue being fixed or feature implemented
We just had a sb voting period and I noticed that the network is way too spammy and produces too many votes (10x+ the expected numbers). It turns out that relying on `ProcessVoteAndRelay` on mainnet is not enough because rate-check expires too soon and MNs are able to vote again and again. On testnet it was never an issue because the voting period there is really short.
## What was done?
Check known votes to make sure we never voted earlier.
## How Has This Been Tested?
Run tests, run a MN on mainnet and check logs.

Pull request description:
## Additional Information
* In [bitcoin#22955](https://github.com/bitcoin/bitcoin/pull/22955), `fBlocksOnly` has not been renamed to `reject_tx_invs` as Dash uses the inventory system beyond relaying transaction data with the block-relay-only blocklist have a greater set of prohibited messages. This renders the new name misleading but coining a new name may be a source of confusion, making retaining the legacy name desirable.
* Additionally, because the word "transaction" isn't hardcoded into the log message (instead opting to use `CInv::GetCommand()`'s output instead, which for transactions, are "tx"), the expected log message in `p2p_blocksonly.py` has been adjusted accordingly.
* [bitcoin#24358](https://github.com/bitcoin/bitcoin/pull/24358) depends on [bitcoin#22955](https://github.com/bitcoin/bitcoin/pull/22955) and [bitcoin#23375](https://github.com/bitcoin/bitcoin/pull/23375) in order to work as without the latter backport, `interface_usdt_utxocache.py` will return the following error

* In [bitcoin#24358](https://github.com/bitcoin/bitcoin/pull/24358), all `interface_usdt_*.py` tests needed minor syntax changes to account for how we invoke certain RPCs. `interface_usdt_utxocache.py` required tweaking with the blocks needed to be eligible for pruning (`450` vs. `350` upstream) and stop the node explicitly to account for the governance validation warning .
This is important as the placement assumes that `test_flush()` is the last test, should this change, the node may need to be manually started before continuing on with the tests after.
* Some `TRACE*` entries may not exactly match the backports they come from because the variables or functions they access may have been amended by a backport done _after_ the backport that introduce the trace entry.

Txout-s in `creditOutputs` for AssetLock txes should be shown the way txout-s are shown in other places. We should not be using debug strings there.

kudos to @coolaj86 for finding the issue
## What was done?
Change `CAssetLockPayload::ToJson()` output to be closer to [`TxToUniv()`](https://github.com/dashpay/dash/blob/develop/src/core_write.cpp#L262-L272)
NOTE: `refactor: use key_to_p2pkh_script in more places` commit is a bit unrelated but I decided to add it anyway to make it easier to follow assetlock creation vs getrawtransaction rpc check.
## How Has This Been Tested?
Try example above, run tests
## Breaking Changes
RPC output is different for AssetLock txes

Pull request description:
## Additional Information
* In [bitcoin#22831](https://github.com/bitcoin/bitcoin/pull/22831), when restarting the node in `rpc_net.py`'s `test_addpeeraddress()`, existing commands need to be appended to `extra_args` to ensure they're retained when the node is restarted (default behavior is to overwrite the argument list with `extra_args`) to prevent the test from hanging and then failing due to missing fast DIP3 activation params from the arguments list.
Missing arguments result in a block database sanity check failure on restart due to `bad-qc-premature` arising from the activation height being higher than the height of a block with a quorum commitment.
* `NodeContext` was moved from `TestingSetup` to `BasicTestingSetup` in [bitcoin#18571](https://github.com/bitcoin/bitcoin/pull/18571) ([dash#4844](https://github.com/dashpay/dash/pull/4844)) but `connman` as a `BasicTestingSetup` variable still stuck around (despite `NodeContext`'s presence making this unnecessary).
To prepare for [bitcoin#22910](https://github.com/bitcoin/bitcoin/pull/22910), the remnant variable has been replaced with `m_node.connman` and adjustments have been made to that effect.

* Dependent on https://github.com/dashpay/dash/pull/6233
* `p2p_ibd_txrelay.py` was first introduced in [bitcoin#19423](https://github.com/bitcoin/bitcoin/pull/19423) to test feefilter logic but on account of Dash not having feefilter capabilities, that backport was skipped over but on account of the tests introduced in [bitcoin#21327](https://github.com/bitcoin/bitcoin/pull/21327) that test capabilities present in Dash, a minimal version of `p2p_ibd_txrelay.py` has been committed in.
* `vSendMsg` is originally a `std::deque` and as an optimization, was changed to a `std::list` in 027a852a ([dash#3398](https://github.com/dashpay/dash/pull/3398)) but this renders us unable to backport [bitcoin#26844](https://github.com/bitcoin/bitcoin/pull/26844) as it introduces build failures. The optimization has been reverted to make way for the backport.

* The collection of `CNode` pointers in `CConnman::SocketHandlerConnected` has been changed to a `std::set` to allow for us to erase elements from `vReceivableNodes` if the node is _also_ in the set of sendable nodes and the send hasn't entirely succeeded to avoid a deadlock (i.e. backport [bitcoin#27981](https://github.com/bitcoin/bitcoin/pull/27981))
* When backporting [bitcoin#28165](https://github.com/bitcoin/bitcoin/pull/28165), `denialofservice_tests` has been modified to still check with `vSendMsg` instead of `Transport::GetBytesToSend()` as changes in networking code to support LT-SEMs (level-triggered socket events mode) mean that the message doesn't get shifted from `vSendMsg` to `m_message_to_send`, as the test expects.
* Specifically, the changes made for LT-SEM support result in the function responsible for making that shift (`Transport::SetMessageToSend()` through `CConnman::SocketSendData()`), not being called during the test runtime.
* As checking `vSendMsg` (directly or through `nSendMsgSize`) isn't enough to determine if the queue is empty, we now also check with `to_send` from `Transport::GetBytesToSend()` to help us make that determination. This mirrors the change present in the upstream backport ([source](https://github.com/bitcoin/bitcoin/pull/28165/files#diff-00021eed586a482abdb09d6cdada1d90115abe988a91421851960e26658bed02R1324-R1327)).
## Breaking Changes
* `bandwidth.message.*.bytesSent` will no longer include overhead and will now only report message size as specifics that let us calculate the overhead have been abstracted away.
