Backporting Statoshi and bitcoin#16728 (#2515)
* Backport Statoshi

This backports some of https://github.com/jlopp/statoshi.

Missing stuff: README.md and client name changes, segwit and fee estimation stats.

Fix RejectCodeToString

Fix copy-paste mistake s/InvalidBlockFound/InvalidChainFound/

* Merge #16728: move-only: move coins statistics utils out of RPC

8a3b2eb17572ca2131778d52cc25ec359470a90f move-only: move coins statistics utils out of RPC (James O'Beirne)

Pull request description:

  This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):

  Parent PR: #15606
  Issue: #15605
  Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal

  ---

  In the short-term, this move-only commit will help with fuzzing (https://github.com/bitcoin/bitcoin/pull/15606#issuecomment-524482297). Later, these procedures will be used to compute statistics (particularly a content hash) for UTXO sets coming in from snapshots.

  Most easily reviewed with `git ... --color-moved=dimmed_zebra`. A nice follow-up would be adding unittests, which I'll do if nobody else gets around to it.

* Fix 16728

* Modernize StatsdClient

- Reuse some functionality from netbase
- Switch from GetRand to FastRandomContext
- Drop `using namespace std` and add `// namespace statsd`

* Introduce PeriodicStats and make StatsdClient configurable via -stats<smth> (enabled/host/port/ns/period)

* Move/rename tip stats from CheckBlock to ConnectBlock

* Add new false positives to lint-format-strings.py

* Add snprintf in statsd_client to the list of known violations in lint-locale-dependence.sh

* Fix incorrect include guard

* Use bracket syntax includes

* Replace magic numbers with defaults

* Move connection stats calculation into its own function

And bail out early if stats are disabled

* assert in PeriodicStats

llmq: Restrict ShouldSimulateError to trigger for LLMQ_TEST only (#3871)
* llmq: Restrict `ShouldSimulateError` to trigger for LLMQ_TEST only

Current `develop` tests fail. This was basically introduced by dashpay#3844 but it didn't come up before dashpay#3853 because the `v17` fork wasn't activated in `feature_llmq_dkgerrors.py`.

After  dashpay#3853 `dip0008` activation takes [200 blocks](b95cf017c3 (diff-4a04bc0b355c780033960e8c261ee9b6d3c452897e1dcd88a15d272512266c76R539)) which was normally activated after [10 blocks](b95cf017c3 (diff-b92fa0fafafa27172736ebc88f9f9b658b1160caca512a318eefb7d93d22bf3cL18)) in `feature_llmq_dkgerrors.py`. Now with the 200 blocks `v17` gets activated during test which then leads to MN1, MN2 banning MN0 because it lies in DKG of `LLMQ_TEST` and `LLMQ_TEST_V17`.

There are other ways to solve it, like enabling `dip0008` earlier or enable `v17` later but IMO its anyway better to restrict `ShouldSimulateError` to only trigger for `LLMQ_TEST`.

* Revert "llmq: Restrict `ShouldSimulateError` to trigger for LLMQ_TEST only"

This reverts commit ec42d86126.

* llmq: Restrict `ShouldSimulateError` to trigger for LLMQ_TEST only (alternative)

Move ShouldSimulateError into CDKGSession

bls: Refactor CBLSWrapper::SetBuf and CBLSWrapper::GetBuf (#3867)
* bls: Add CBLSImplicit, a wrapper around uint256

This makes `CBLSImplicit` compatible (related to methods called by
CBLSWrapper) with the other classes from the
bls-signatures library.

* bls: Use CBLSImplicit instead of uint256 as base type of CBLSId

* bls: Use FromBytes directly instead of indirectly through InternalSetBuf

* bls: Use Serialize directly instead of indirectly through InternalGetBuf

* bls: Drop all occurrences of InternalSetBuf and InternalGetBuf

* bls: Use `CBLSIdImplicit` instead of `uint256` in some more places
