fa6e01b2f3cd8523a95bd1906ac5e62ee3cbf319 ci: Use clang-8 for fuzzing to run on aarch64 ci systems (MarcoFalke)
Pull request description:
Ubuntu bionic clang is clang version 6, which does not come with libfuzzer. So the ci system breaks down when run on aarch64.
Fix that by using clang-8
For reference, the previous error on my ci system was:
```

b51bae1a5a4fa8ef7825dd1bb09e3f47f96d7a5a doc: minor corrections in random.cpp (fanquake)
Pull request description:
This introduces a new `randomenv` module that queries varies non-cryptographic (and non-RNG) sources of entropy available on the system; things like user IDs, system configuration, time, statistics, CPUID data.
The idea is that these provide a fallback in scenarios where system entropy is somehow broken (note that if system entropy *fails* we will abort regardless; this is only meant to function as a last resort against undetected failure). It includes some data sources OpenSSL currently uses, and more.
The separation between random and randomenv is a bit arbitrary, but I felt that all this "non-essential" functionality deserved to be separated from the core random module.

Remove the `(64-bit)` from the bitcoin-qt help message.
Since removing the Windows 32-bit builds, it is no longer information
that is often useful for troubleshooting. This never worked for other
architectures than x86, and the only 32-bit x86 build left is the Linux
one. Linux users tend to know what architecture they are using.
It also accidentally ends up in the bitcoin-qt manpage.

The test uses reinterpret_cast<void*> on unallocated memory. Using this
memory in printchunk as char* causes a segfault, so have printchunk take
void* instead.
The definition and uses of Arena::walk() are compiled only if
ARENA_DEBUG is defined. Configure Travis to define ARENA_DEBUG so
compilation errors do not go unnoticed.
Changes in #12048 cause a compilation error in Arena::walk() when
ARENA_DEBUG is defined. Specifically, Arena's chunks_free map was
changed to have a different value type.
Additionally, missing includes cause other compilation errors when
ARENA_DEBUG is defined.
Reproduced with:

18b18f8e813b332d0ce6b0af19c9cb265f043776 [build] ./configure --enable-werror: add unused-variable (Sjors Provoost)
Pull request description:
The two macOS Travis machines run with `--enable-werror`. This PR adds `-Werror=unused-variable` to the existing `vla`, `switch` and `thread-safety-analysis` checks. This should prevent the need for fixes like b07b07cd8779355ba1dd16e7eb4af42e0ae1c587, 26a93bce29fd813e1402b013f402869c25b656d1, dd777f3e1220dd1a76e8a29cafdd4fe6244c5c0f, 99be644966c63e9917161f97574905551e44360f, fa39f674aed8f2dc5a9bde6a84b0ec52fc49e695, 16bcc1b8237698c96b8ced2fa7eb76388c7ba85e, bb079a0e2c20beb22456c91ad9e11beeae7cdc34, bdaed4755846e8b1e533c14485faa5f9fd1cf18b and ecf9b25a03d8a29f16005ca4485b6533db6efc82 with minimal nuisance.
Thoughts for followups:
* Travis starts these macOS machines fairly late, so we should consider setting `--enable-werror` on earlier machines as well.
* We should encourage the use of `--enable-werror` by developers. Maybe switch it on by default for `--enable-debug`?
* See practicalswift's overview of other checks to consider in #17344

Currently it is an alias to the global ::mempool and should be used as
follows.
* Node code (validation and transaction relay) can use either ::mempool
or node.mempool, whichever seems a better fit.
* RPC code should use the added convenience getter EnsureMempool, which
makes sure the mempool exists before use. This prepares the RPC code
to a future where the mempool might be disabled at runtime or compile
time.
* Test code should use m_node.mempool directly, as the mempool is always
initialized for tests.

Also rename the "result_complete" variable in GetSettingsList() to "done" to be
more consistent with GetSetting().
This change doesn't affect current behavior but could be useful in the future
to support dynamically changing settings at runtime and adding new settings
sources, because it lets high priority sources reset settings back to default
(see test).
By removing a special case for null, this change also helps merge code treat
settings values more like black boxes, and interfere less with settings parsing
and retrieval.

detail not meant to be used by ArgsManager callers.

need to call GetArgFlags (https://github.com/bitcoin/bitcoin/pull/16545)

* Instead of calling RandAddSeedSleep anytime the scheduler goes
idle, call its replacement (RandAddSeedPeriodic) just once per
minute. This has better guarantees of actually being run, and
helps limit how frequently the dynamic env data is gathered.
* Since this code runs once per minute regardless now, we no
longer need to keep track of the last time strengthening was
run; just do it always.
* Make strengthening time context dependent (100 ms at startup,
10 ms once per minute afterwards).
