8e55981ef834490c438436719f95cbaf888c4914 refactor: replace Boost shared_mutex with std shared_mutex in cuckoocache tests (fanquake)
Pull request description:
This replaces `boost::shared_mutex` and `boost::unique_lock` with [`std::shared_mutex`](https://en.cppreference.com/w/cpp/thread/shared_mutex) & [`std::unique_lock`](https://en.cppreference.com/w/cpp/thread/unique_lock).
Even though [some concerns were raised](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) in #16684 with regard to `std::shared_mutex` being unsafe to use across some glibc versions, I still think this change is an improvement. As I mentioned in #21022, I also think trying to restrict standard library feature usage based on bugs in glibc is not only hard to do, but it's not currently clear exactly how we do that in practice (does it also extend to patching out use in our dependencies, should we be implementing more runtime checks for features we are using, when do we consider an affected glibc "old enough" not to worry about? etc). If you take a look through the [glibc bug tracker](https://sourceware.org/bugzilla/describecomponents.cgi?product=glibc) you'll no doubt find plenty of (active) bug reports for standard library code we already using. Obviously not to say we shouldn't try and avoid buggy code where possible.
Two other points:
[Cory mentioned in #21022](https://github.com/bitcoin/bitcoin/pull/21022#issuecomment-769274179):
> It also seems reasonable to me to worry that boost hits the same underlying glibc bug, and we've just not happened to trigger the right conditions yet.
Moving away from Boost to the standard library also removes the potential for differences related to Boosts configuration. Boost has multiple versions of `shared_mutex`, and what you end up using, and what it's backed by depends on:
* The version of Boost.
* The platform you're building for.
* Which version of `BOOST_THREAD_VERSION` is defined: (2,3,4 or 5) default=2. (see [here](https://www.boost.org/doc/libs/1_70_0/doc/html/thread/build.html#thread.build.configuration) for some of the differences).
* Is `BOOST_THREAD_V2_SHARED_MUTEX` defined? (not by default). If so, you might get the ["less performant, but more robust"](https://github.com/boostorg/thread/issues/230#issuecomment-475937761) version of `shared_mutex`.
A lot of these factors are eliminated by our use of depends, but users will have varying configurations. It's also not inconceivable to think that a distro, or some package manager might start defining something like `BOOST_THREAD_VERSION=3`. Boost tried to change the default from 2 to 3 at one point.
With this change, we no longer use Boost Thread, so this PR also removes it from depends, the build system, CI etc.
Previous similar PRs were #19183 & #20922. The authors are included in the commits here.

fd0be92cff6a4b5e343e6ddae7481868354b9869 doc: Add instructions on how to fuzz the P2P layer using Honggfuzz NetDriver (practicalswift)
Pull request description:
Add instructions on how to fuzz the P2P layer using [Honggfuzz NetDriver](http://blog.swiecki.net/2018/01/fuzzing-tcp-servers.html).
Honggfuzz NetDriver allows for very easy fuzzing of TCP servers such as Bitcoin Core without having to write any custom fuzzing harness. The `bitcoind` server process is largely fuzzed without modification.
This makes the fuzzing highly realistic: a bug reachable by the fuzzer is likely also remotely triggerable by an untrusted peer.

Also, the compiler is now able to use `-Wswitch`.

Pull request description:
When trying to send a transaction from an encrypted wallet, the ask
passphrase dialog would not allow the user to click the "OK" button
and proceed. Therefore it was impossible to send a transaction
through the gui. It was not enabling the "OK" button after the
passphrase was entered by the user, because it was using the same
form validation logic as the "Change passphrase" flow.
I reported this in a comment in https://github.com/bitcoin-core/gui/issues/136. But then I realized this seems to be a flat out bug.

11e79084845a78e2421ea3abafe0de5a54ca2bde prevector: only allow trivially copyable types (Martin Leitner-Ankerl)
Pull request description:
prevector uses `memmove` to move around data, that means it can only be used with types that are trivially copyable. That implies that the types are trivially destructible, thus the checks for `is_trivially_destructible` are not needed.

Pull request description:
Since v4.3.3 (068385c951) `libzmq` uses `libbsd` by default.
This PR disables `libbsd` explicitly, as it's not a part of our depends. Zeromq will fallback to its internal `strlcpy` implementation.
Otherwise, on systems with installed `libbsd-dev` package the `zeromq` package build system erroneously detects `libbsd` package from the host system:
```diff

This causes the `configure` fails to detect the `zeromq` package:
```

```
---
Other minor improvements:
- fixed `netbsd_kevent_void.patch` offset

64e1ddd255771e57a88a20f07dbde04a83bf0c75 log: call LogPrint only once with time data samples (Martin Zumsande)
Pull request description:
When timedata samples are logged, `LogPrint()` is currently invoked multiple times on the same log entry.
This can lead to chaos in the log when other threads log concurrently, as in this example which motivated this PR:
```
2021-09-20T00:28:57Z -48 -26 -11 -8 -6 Addrman checks started: new 37053, tried 83, total 37136
2021-09-20T00:28:57Z -3 -1 -1 -1 -1 +0 | nTimeOffset = -3 (+0 minutes)
```
Fix this by building the log message in a string and logging it one `LogPrint()` call. I also changed the wording slightly so that it becomes understandable what is being logged, example:
```
2021-09-21T21:03:24Z time data samples: -43 -18 -12 -4 -1 -1 +0 +0 +268 | median offset = -1 (+0 minutes)

Pull request description:
The comment seems to be describing the subsequent call to `SyncTransaction` but refers to it as `SyncNotifications`, which is not any function currently in the codebase.
It's best to just remove the "what" aspect of the comment and focus on the "why", which also reduces the risk of similar documentation errors in the future, in case the function ever gets renamed, for example.

2ea62cae483b764e30f61c06d8ac65755bbd864c Improve docs about feeler connections (Gleb Naumenko)
Pull request description:
"feeler" and "test-before-evict" are two different strategies suggest in [Eclipse Attacks on Bitcoin’s Peer-to-Peer Network](https://www.usenix.org/system/files/conference/usenixsecurity15/sec15-paper-heilman.pdf). In our codebase, we use `ConnType::FEELER` to implement both.
It is confusing, up to the point that our documentation was just incorrect.
This PR:
- ~clarifies this aspect by renaming "ConnType::FEELER" to "ConnType::PROBE", meaning that this connections only probes that the node is operational, and then disconnects.~
- fixes the documentation

## Issue being fixed or feature implemented
Client version string is inconsistent. Building `v20.0.0-beta.8` tag
locally produces binaries that report `v20.0.0-beta.8` version but
binaries built in guix would report
`v20.0.0rc1-g3e732a952226a20505f907e4fd9b3fdbb14ea5ee` instead. Building
any commit after `v20.0.0-beta.8` locally would result in versions like
`v20.0.0rc1-8c94153d2497` which is close but it's still yet another
format. And both versions with `rc1` in their names are confusing cause
you'd expect them to mention `beta.8` instead maybe (or is it just me?
:D ).
## What was done?
Change it so that the version string would look like this:
on tag: ~`v20.0.0-beta.8-dev` or `v20.0.0-beta.8-gitarc`~
`v20.0.0-beta.8`
post-tag: ~`v20.0.0-beta.8-1-gb837e08164-gitarc`~
`v20.0.0-beta.8-1-gb837e08164`
post-tag format is
`recent tag`-`commits since that tag`-`g+12 chars of commit hash`-`dirty
(optional)` ~-`dev or gitarc`~
~`dev`/`gitarc` suffixes should help avoiding confusion with the release
versions and they also indicate the way non-release binaries were
built.~
Note that release binaries do not use any of this, they still use
`PACKAGE_VERSION` from `configure` like before.
Also, `CLIENT_VERSION_RC` is no longer used in this setup so it was
removed.
Few things aren't clear to me yet:
1. Version bump in `configure.ac` no longer affects the reported version
(unless it's an actual release). Are there any downsides I might be
missing?
2. Which tag should we use on `develop` once we bump version in
configure? `v21.0.0-init`? `v21.0.0-alpha1`?
3. How is it going to behave once `merge master back into develop` kind
of PR is merged? E.g. say `develop` branch is on `v21.0.0-alpha1` tag
and we merge v20.1.0 from `master` back into it. Will this bring
`v20.1.0` release tag into `develop`? Will it become the one that will
be used from that moment? If so we will probably need another tag on
`develop` every time such PR is merged e.g. `v21.0.0-alpha2` (or
whatever the next number is).
Don't think these are blockers but would like to hear thoughts from
others.
## How Has This Been Tested?
Built binaries locally, built them using guix at a specific tag and at
some commit on top of it.
