aee5404e02e203a256c1a97b629b9b107cc8bb07 Add support for RNDR/RNDRRS for aarch64 on Linux (John Moffett)
Pull request description:
This checks whether the ARMv8.5-A optional TRNG extensions [RNDR](https://developer.arm.com/documentation/ddi0601/2022-12/AArch64-Registers/RNDR--Random-Number) and [RNDRRS](https://developer.arm.com/documentation/ddi0601/2022-12/AArch64-Registers/RNDRRS--Reseeded-Random-Number) are available and, if they are, uses them for random entropy purposes.
They are nearly functionally identical to the x86 RDRAND/RDSEED extensions and are used in a similar manner.
Currently, there [appears to be](https://marcin.juszkiewicz.com.pl/download/tables/arm-socs.html) only one actual hardware implementation -- the Amazon Graviton 3. (See the `rnd` column in the link.) However, future hardware implementations may become available.
It's not possible to directly query for the capability in userspace, but the Linux kernel [added support](1a50ec0b3b) for querying the extension via `getauxval` in version 5.6 (in 2020), so this is limited to Linux-only for now.
Reviewers may want to launch any of the `c7g` instances from AWS to test the Graviton 3 hardware. Alternatively, QEMU emulates these opcodes for `aarch64` with CPU setting `max`.
Output from Graviton 3 hardware:

This partially closes#26796. As noted in that issue, OpenSSL [added support](https://github.com/openssl/openssl/pull/15361) for these extensions a little over a year ago.

Pull request description:
When calculating a median fee for a confirmation target at a particular threshold, we analyse buckets in ranges rather than individually in case some buckets have very little data. This patch ensures the breaks between ranges are independent of the the confirmation target.

6bdff429ec17eae4138c3af1e21de3ec46f4ab13 build: Include `config/bitcoin-config.h` explicitly in `util/trace.h` (Hennadii Stepanov)
Pull request description:
The `ENABLE_TRACING` macro is expected to be defined in the `config/bitcoin-config.h` header.
Therefore, the current code is error-prone as it depends on whether the `config/bitcoin-config.h` header was included before or not.
This bug was noticed while working on CMake [stuff](https://github.com/hebasto/bitcoin/pull/37).

8fcbdadfad8a9b3143527141ff37e5fe1e87f3b3 util: fix argsman dupe key error (willcl-ark)
Pull request description:
fixes#22638
Make GUI "Settings file could not be read. Do you want to reset settings to default values?" dialog actually clear all settings instead of partially keeping them when `settings.json` contains duplicate keys. This change has no effect on `bitcoind` because it treats a corrupt `settings.json` file as a hard error and doesn't attempt to modify it.
If we find a duplicate key and error, clear `values` before returning so that `WriteSettings()` will write an empty file, therefore clearing it.
This aligns with GUI behaviour added in 1ee6d0b.
The test added only checks that `values` is empty after a duplicate key is detected. This paves the way for the `abort` option in the GUI to properly clear `settings.json`, if the user selects the option, but the test does not currently check this entire mechanism (e.g. the file contents).

54c4d03578c5842f19bf8bc68aca5faf8beed5c3 doc: Show how less noisy clang-tidy output can be achieved (TheCharlatan)
Pull request description:
Adds a paragraph to the clang-tidy section explaining how to de-noise its output. By default clang-tidy will print errors arrising from included headers in leveldb and other dependencies. By passing `--enable-suppress-external-warnings` flag to configure, errors arising from external dependencies are suppressed. Additional errors arrising from internal dependencies such as leveldb are suppressed by passing the `src/.bear-tidy-config` configuration file to bear. This file includes exclusionary rules for leveldb.

5c938e74cfdf6b89c6c4d5cce2fd07cbfc8b29c2 Use string interpolation for default value of -listen (ekzyis)
Pull request description:
This is a refactoring change. So I have read the following and will try to answer why this change should be accepted
> * 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.
I have noticed in https://github.com/bitcoin/bitcoin/pull/26899#discussion_r1086731856 that the helper message for `-listen` does not use string interpolation.
That confused me and I wasn't sure what the reasons for that are. So it could be argued this confusion (by possibly many people in the past and in the future) may already be enough to accept this change.
However, not accepting this means that if `DEFAULT_LISTEN` is ever changed, this helper message will still use the old value (however unlikely that may be).
Therefore, this PR makes the helper message consistent with how other helper messages are implemented (using string interpolation) which leads to less confusion and prevents possibly wrong documentation in the future.

Pull request description:
ping hebasto
Discovered while testing pre-compiled header support with CMake: https://github.com/theuni/bitcoin/commits/cmake-pch-poc. Compilation of that branch fails without this fix and succeeds with it.
Similar to the fix in #27144.
The problem of having a default argument in the definition was masked by the missing include. Using PCH forces that include, so we end up with the compiler error we should've been getting all along.

63e90e1d3f5ed08f9871f07667d389ec66aa621c test: check for specific disconnect reasons in p2p_blockfilters.py (Sebastian Falbesoner)
Pull request description:
This PR checks for specific disconnect reasons using `assert_debug_log` in the functional test `p2p_blockfilters.py`. With that we ensure that the disconnect happens for the expected reason and also makes it easier to navigate between implementation and test code, i.e. both the questions "do we have test coverage for this disconnect cause?" (from an implementation reader's perspective) and "where is the code handling this disconnect cause?" (from a test reader's perspective) can be answered simply by grep-ping the corresponding debug message.
Also, based on that, missing coverage for the (start height > stop height) disconnect case is added:

508d05f8a7b511dd53f543df8899813487eb03e5 [fuzz] Don't use afl++ deferred forkserver mode (dergoegge)
Pull request description:
Fixes#28469
This makes our afl++ harness essentially behave like libFuzzer, with the exception that the whole program does fully reset every 100000 iterations. 100000 is somewhat arbitrary and we could also go with `std::numeric_limits<unsigned in>::max()` but a smaller limit does allow for the occasional reset to counter act some amount of instability in the fuzzing loop (e.g. non-determinism, statefulness).
It's a bit of a shame to do this just for the targets whose initial state can't be forked (e.g. threads) because other targets do benefit from not having to redo the state setup. An alternative would be https://github.com/bitcoin/bitcoin/issues/28469#issuecomment-1717526774:
```
If the goal is to be maximally performant, the fork would need to happen for each fuzz target specifically.
I guess it can be achieved by wrapping __AFL_INIT(); into a helper function and then require all fuzz
target initialize() to call it?

fbcacd4cf0dbe54e51f89cda05ff3db9e378ea12 test: remove fixed timeouts from feature_config_args (Martin Zumsande)
Pull request description:
Fixes#28290
These fixed timeouts aren't affected by the `timeout_factor` option and can therefore cause timeouts in slow environments.
They are also unnecessary for the test because they measure the wrong thing:
While there is an internal waiting time of 60s within `ThreadOpenConnections` (beginning only when that thread is started) for fixed seeds querying, the timeouts here don't measure that but the time from startup until a debug log message is encountered, during which many other things happen in init, so they don't make much sense to me in the first place.

360ac64b90ee16cc24bd4c574ec7e11760515a79 test: previous releases: speed up fetching sources with shallow clone (Sebastian Falbesoner)
Pull request description:
For the sake of building previous releases, fetching the whole history of the repository for each version seems to be overkill as it takes much more time, bandwidth and disk space than necessary. Create a shallow clone instead with history truncated to the one commit of the version tag, which is directly checked out in the same command. This has the nice side-effect that we can remove the extra `git checkout` step after as it's not needed anymore.
Note that it might look confusing to pass a _tag_ to a parameter named `--branch`, but the git-clone manpage explicitly states that this is supported.

c5f6b1db56f67f529377bfb61f58c0a8c17b0127 fuzz: coins_view: correct an incorrect assertion (Antoine Poinsot)
Pull request description:
The `coins_view` fuzz target would assert in two places that the cache is consistent with the backend. But it's never the case (that's the whole point of using a cache).
The only reason this didn't result in a crash was that we would never actually hit these assertions. I ran into this while introducing a new target with an in-memory `CCoinsViewDB` as the backend view (see https://github.com/bitcoin/bitcoin/pull/28216) which made the code paths with those assertions actually reachable.

Pull request description:
This simplifies the serialization code a bit and should also make it a bit faster.
* use fold expressions instead of recursive calls. This simplifies the code, makes it most likely faster because it reduces the number of function calls, and compiles faster because there are fewer template instantiations.
* use `if constexpr` instead of unnecessarily creating a temporary object only to call the right overload. This is used for `std::vector` and `prevector` serialization.

Similarly to https://github.com/bitcoin/bitcoin/pull/29458, we're preallocating the result string based on the input string's length.
The methods were already [covered by tests](https://github.com/bitcoin/bitcoin/blob/master/src/test/util_tests.cpp#L1250-L1276).
