`RawSender` is inspired by `UDPSender` from `vthiery/cpp-statsd-client`
and separating it out of `StatsdClient` is needed to implement queueing
and batching support in upcoming commits.
This is the start of migrating our Statsd codebase to `cpp-statsd-client`.
In upcoming commits, message sending will be split off into a separate
file and stats capabilities will be fleshed out. Prepare for that by
giving it its own directory.
Also get rid of `statsd` namespace, it is entirely unnecessary.

## Additional Information
Support for transmitting stats to a Statsd server has been courtesy of Statoshi ([repo](https://github.com/jlopp/statoshi)), implemented Dec, 2020 by [dash#2515](https://github.com/dashpay/dash/pull/2515) but since then, it hasn't gotten much attention aside from benefiting from codebase-wide changes and the occasional compiler appeasement. This pull request aims to give our statistics code some TLC.
Changes include:
* Limiting initialization to solely during construction and moving the responsibility of fetching arguments outside of `statsd::StatsdClient`.
* Using the RAII `Socks` wrapper as early as possible (we still need to construct a raw socket ourselves but this is done in the initializer and control is moved to the wrapper and everywhere else, the wrapper is used)
* Utilizing existing networking code to generate the socket address
* This lets us trivially allow IPv6 connections as the responsibility to construct it safely is moved to `CService`.
* Using `std::string` and our string manipulation capabilities (replacing `snprintf` with `strprintf`), replacing platform-specific types (replacing `short` with `uint16_t`).

## Additional Information
* When backporting [bitcoin#23054](https://github.com/bitcoin/bitcoin/pull/23054), `sigOpCount` and `nSigOpCountWithAncestors` were switched from `unsigned int` to `int64_t`. This change was done to prevent integer narrowing when accepting the `int64_t` taken from the constructor.
This isn't a problem upstream as the same changes were as part of [bitcoin#8149](https://github.com/bitcoin/bitcoin/pull/8149/files#diff-8a2230436880b65a205db9299ab2e4e4adb1d4069146791b5db566f3fb752adaL90-L107), which was omitted but the type changes remain valid as sigop count cannot be a negative number.

As creating the socket is now the last step, we don't need
`m_init` anymore. We can just see if a socket is successfully
constructed and take that as our validity indicator.
We'll also move it out of the inner `send` function so we can bail out
before we bother with all the string processing and manipulation.
We can skip the computationally expensive dice-roll if our sample rate
is zero as that means we should never send it. Also get rid of the
`FastRandomContext::operator()` that isn't used anywhere else in the
codebase.
- Use `uint16_t` instead of `short`, `int64_t` instead of `size_t`
- Get rid of the `errmsg` buffer and use `LogPrintf` to report errors
- Use `strprintf` instead of `snprintf`
- Rephrase networking error logs to allow inclusion of error strings

1937f503fe feat: regtest-only: do not auto-reset mnsync after 1h (UdjinM6)
Pull request description:
## Issue being fixed or feature implemented
1. The original idea behind forced reset was to help desktop clients which go into sleep/hibernation mode from time to time to sync with no issues once they are online again. For regtest however it doesn't do anything good and only causes issues.
2. We rely on schedulers a lot, bumping them should let nodes behave more like on a real network.
3. Forcing mnsync to skip governance votes doesn't always work as we'd expect cause we don't control connection creation. To make it more deterministic create a proposal that should get into one superblock only. This way both the proposal and the trigger will expire/be deleted after another superblock meaning we can be 100% sure the isolated node never gets any of them and can only sync thanks to chainlock.

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.

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.

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.

## 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

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
