6cbe6209646db8914b87bf6edbc18c6031a16f1e scripted-diff: Replace CCriticalSection with RecursiveMutex (MarcoFalke)
Pull request description:
`RecursiveMutex` better clarifies that the mutex is recursive, see also the standard library naming: https://en.cppreference.com/w/cpp/thread/recursive_mutex
For that reason, and to avoid different people asking me the same question repeatedly (e.g. https://github.com/bitcoin/bitcoin/pull/15932#pullrequestreview-339175124 ), remove the outdated alias `CCriticalSection` with a scripted-diff

7851f14ccf2bcd1e9b2ad48e5e08881be06d9d21 rpc: incorporate review feedback from PR 17283 (Jon Atack)
Pull request description:
This PR builds on #17283 (now merged) and is followed by #17585.
It modifies the value returned by rpc getaddressinfo `labels` to an array of label name strings and deprecates the previous behavior of returning an array of JSON hash structures containing label `name` and address `purpose` key/value pairs.
before
```
"labels": [
{
"name": "DOUBLE SPEND",
"purpose": "receive"
}
```
after
```
"labels": [
"DOUBLE SPEND"
]
```
The deprecated behavior can be re-enabled by starting bitcoind with `-deprecatedrpc=labelspurpose`.
For context, see:
- https://github.com/bitcoin/bitcoin/pull/17283#issuecomment-554458001
- http://www.erisian.com.au/bitcoin-core-dev/log-2019-12-13.html#l-425 (lines 425-427)
- http://www.erisian.com.au/bitcoin-core-dev/log-2019-11-22.html#l-622
Reviewers: This PR may be tested manually by building, then running bitcoind with and without the `-deprecatedrpc=labelspurpose` flag while verifying the rpc getaddressinfo help text and `labels` output.
Next steps: deprecate the rpc getaddressinfo `label` field (EDIT: done in #17585) and add support for multiple labels per address. This PR will unblock those.

Pull request description:
This PR is a continuation of the work in https://github.com/bitcoin/bitcoin/pull/12892.
Main motivations:
- There is currently no test coverage for the getaddressinfo `labels` response. Coverage here is a prerequisite before deprecating the `label` response or adding multiple labels per address.
- `bitcoin-cli help getaddressinfo` returns a few content errors, difficult-to-read formatting, and no explanation why it returns both `label` and `labels` and how they relate, which can be confusing for application developers.
Changes by order of commits:
- [x] improve/fix getaddressinfo RPCHelpman layout formatting
- [x] improve/fix getaddressinfo RPCHelpman content
- [x] clarify the `label` and `labels` fields in getaddressinfo RPCHelpman
- [x] update getaddressinfo RPCExamples addresses to bech32
- [x] add getaddressinfo code docs
- [x] add a `listlabels` test assertion in wallet_labels.py
- [x] add missing getaddressinfo `labels` test coverage and improve the existing `label` tests
Here are gists of the CLI help output:
[`bitcoin-cli help getaddressinfo` before this PR](https://gist.github.com/jonatack/022af5221a85c069780359a22643c810)
[`bitcoin-cli help getaddressinfo` after this PR](https://gist.github.com/jonatack/4ee5f6abc62a3d99269570206a5f90ba)
It seems we ought to begin a deprecation process for the getaddressinfo `label` field? If yes, I have a follow-up ready. _--> EDIT: Deprecation follow-ups #17578 and #17585 now build on this PR._
