b51bae1a5a 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.

utACK d1c02775aa. Certainly no longer measuring the time elapsed between a 1ms sleep (which got removed in the latest change) is a fair tradeoff for adding about 2 million other actually-higher-entropy bits :).

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:
make CPPFLAGS=-DARENA_DEBUG
18b18f8e81 [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 b07b07cd87, 26a93bce29, dd777f3e12, 99be644966, fa39f674ae, 16bcc1b823, bb079a0e2c, bdaed47558 and ecf9b25a03 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

The loop is intended to ensure that only a single input exists the entire time until the change output disappears, a single additional bump occurs, then it leaves the loop.

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.

* 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).
49997813a4 test: check custom ancestor limit in mempool_packages.py (Sebastian Falbesoner)
Pull request description:
The functional test `mempool_packages.py` starts one node with default ancestor/descendant limit settings and one with a custom, reduced ancestor limit (currently `-limitancestorcount=5`). The effect of the latter had not been tested yet though. This is approached in this PR by checking on the expected mempool contents of node1 after the node0 ancestor tests are done, via the following three conditions:
- the # of txs in the node1 mempool is equal to the the limit
- all txs in node1 mempool are a subset of txs in node0 mempool
- the node1 mempool txs match the start of the constructed tx-chain
Note that this still doesn't *fully* check the expected mempool of node1 (e.g. that it isn't influenced by `prioritisetransaction` RPC on node0), hence I add another TODO. In the future it would make sense to also set a custom descendant limit when the second TODO about checking node1's mempool is approached: 89e93135ae/test/functional/mempool_packages.py (L228)

To test the custom ancestor limit on node1 (passed by the argument
-limitancestorcount), we check for three conditions:
-> the # of txs in the node1 mempool is equal to the the limit
-> all txs in node1 mempool are a subset of txs in node0 mempool
-> the node1 mempool txs match the start of the constructed tx-chain

<!--
Please provide clear motivation for your patch and explain how it improves
Bitcoin Core user experience or Bitcoin Core developer experience
significantly:
* Any test improvements or new tests that improve coverage are always welcome.
* All other changes should have accompanying unit tests (see `src/test/`) or
functional tests (see `test/`). Contributors should note which tests cover
modified code. If no tests exist for a region of modified code, new tests
should accompany the change.
* Bug fixes are most welcome when they come with steps to reproduce or an
explanation of the potential issue as well as reasoning for the way the bug
was fixed.
* Features are welcome, but might be rejected due to design or scope issues.
If a feature is based on a lot of dependencies, contributors should first
consider building the system outside of Bitcoin Core, if possible.
* Refactoring changes are only accepted if they are required for a feature or
bug fix or otherwise improve developer experience significantly. For example,
most "code style" refactoring changes require a thorough explanation why they
are useful, what downsides they have and why they *significantly* improve
developer experience or avoid serious programming bugs. Note that code style
is often a subjective matter. Unless they are explicitly mentioned to be
preferred in the [developer notes](/doc/developer-notes.md), stylistic code
changes are usually rejected.

<!--
Bitcoin Core has a thorough review process and even the most trivial change
needs to pass a lot of eyes and requires non-zero or even substantial time
effort to review. There is a huge lack of active reviewers on the project, so
patches often sit for a long time.
