634cd60dc8f646b25701c45ac35a1175ce4c4da9 build: Add embedded asmap data (Fabian Jahr)
Pull request description:
This is the final in a series of PRs that implement the necessary changes for embedding of asmap data into the binary. This last part add the initial asmap data, implements the build changes and adds further documentation.
Currently an asmap file needs to be acquired by there user from some location or the user needs to generate one themselves. Then they need to move the file to the right place in datadir or pass the path to the file as `-asmap=PATH` in order to use the asmap feature. The change here allows for builds to embed asmap data into the bitcoind binary which makes it possible to use the feature without handling of the asmap file by the user. If the user starts bitcoind with `-asmap` the embedded data will be used for bucketing of nodes.
The data lives in the repository at `src/node/data/ip_asn.dat` and can be replaced with a new version at any time. The idea is that the data should be updated with every release. By default the data at that location is embedded into the binary but there is also a build option to prevent this (`-DWITH_EMBEDDED_ASMAP=OFF`). In this case the original behavior of the `-asmap` option is maintained.

d79249d2799e7f450d5708ca3366461f5f2069bc ci: add chimera Linux LTO CI job (fanquake)
Pull request description:
Adds a CI config based on using [Chimera Linux](https://chimera-linux.org/). This might be interesting for any of the following:
* Chimera is based on LLVM & musl libc - we test both of these in isolation, but not together.
* No GNU components. I don't think we have an existing Linux CI job that doesn't have a gcc/stdlibc++ install. This exercises the depends logic for a fully LLVM/Clang/lld only build, including building the native tools (related to #33902).
* We don't currently have a job with LTO enabled (here using CMakes `CMAKE_INTERPROCEDURAL_OPTIMIZATION`, which is `-flto=thin` for LLVM/Clang). I think this is worth having generally (we do use LTO in some other places, like oss-fuzz). If runtime is too much of an issue, then it could also be dropped. (Chimera itself is also compiled with LTO).
QT in depends doesn't build (#32744), so is excluded for now.
Chimera has pointed out at least a few quirks, i.e #34390, #34408 and https://github.com/bitcoin/bitcoin/pull/29963#discussion_r2707922298.

The goal of the [patch](https://github.com/bitcoin/bitcoin/blob/master/ci/test/01_iwyu.patch) is to suggest C++ headers rather than their C counterparts. However, for fixed width integer types, the patched IWYU currently suggests `<cinttypes>` where `<cstdint>` is sufficient.

-Werror is added to the previous releases job, given it runs on Ubuntu
22.04, which uses an older CMake.
`--compile-no-warning-as-error` can be used, if needed, in future, to
suppress the `CMAKE_COMPILE_WARNING_AS_ERROR` behaviour from a CI
config.
CMAKE_COMPILE_WARNING_AS_ERROR was added to CMake in 3.24.
See https://cmake.org/cmake/help/latest/prop_tgt/COMPILE_WARNING_AS_ERROR.html.

580e9eefe39f2f94695e1a22437c6ac47a1664e6 ci: bump CCACHE_MAXSIZE to 2G (will)
Pull request description:
Currently some CI jobs don't have great ccache hitrates which we should try to improve: https://willcl-ark.github.io/bitcoin-core-ci-stats/graph/ccache/
- bump ccache maxsize to 2GB in all jobs. We have 150GB shared cache to use, so this should be OK at maximum of 36GB total (current jobset).
- print more verbose ccache stats in the CI logs
The idea is that increasing the cache size to > 2x needed size should eliminate any cache thrashing which might be taking place on master builds when we save the cache. Additionally, larger caches result in more hits in general.

With 15 runners we get 150GB of cache space to use, and we currently
have 18 jobs using ccache.
Although each run only generates ~ 200-300 MB of cache data on each run,
the small the small size may be contributing to poor hitrate.
Bump ccache to 2GB per job ~ --> 36GB of the total 150GB cache space to
try and reduce any thrashaing and generally increase hitrate.

This is used for argument parsing in the retry script, however we don't
use the script with any arguments. So remove the unused code, and the
dependency on gnu-getopt.
This came up in the context of adding new CI jobs, where gnu-getopt
might not be available, or working properly. It seemed easier to just
remove the unused code, than look for more workarounds.

Pull request description:
The number of dropped parent transactions in the `test_max_disconnect_pool_bytes` test was hard-coded to `2`.
This happens to work fine on 64-bit for now. However, it seems to fail on 32-bit (https://github.com/bitcoin/bitcoin/issues/34108).
I don't think we care about the exact number, as long as it is at least `1`.
So hard-code `1` for an initial sanity check, and then calculate the exact value at runtime via `len(mempool) // 2`.
Also, enable the functional tests in 32-bit CI, to confirm the regression test.

This should avoid having to include interfaces/chain.h from a kernel
module. interfaces/chain.h in turn includes a bunch of non-kernel
headers, that break the desired library topology and might introduce
entanglement regressions.
Specifically gets rid of batchpriority, chainparams, script/sign.h and
system includes.
Also take the opportunity of cleaning up the headers for the effected
files and adding them to the iwyu-enforced set.

Pull request description:
The remaining `ci/test/02_run_container.sh` is fine, but has a bunch of shellcheck SC2086 word splitting violations.
This is fine currently, because the only place that needed them had additional escaping, and all other commands happened to split fine on spaces.
However, this may change in the future. So fix it now, by rewriting it in Python, which is recommended in the dev notes.

Pull request description:
Historically, there was an attempt via `test/lint/lint-python-utf8-encoding.py` to enforce explicit UTF8 in every Python IO statement (`open`, `subprocess`, ...). However, the lint check has many problems:
* The check is incomplete and many IO statements lack the explicit UTF8 specification.
* It was added at a time when some systems were not UTF8 by default.
* The check is brittle, as it depends on a fragile regex.
In theory, now that the minimum Python version is 3.10 (since commit 2123c94448ed142e78942421c597a1f264859c48), the check could be replaced by `PYTHONWARNDEFAULTENCODING=1` from https://docs.python.org/3/whatsnew/3.10.html#optional-encodingwarning-and-encoding-locale-option. However, this comes with many other problems:
* All our Python scripts already assume and require UTF8 to be set externally. On almost all modern systems, this is already the default. Some Windows versions do not have UTF8 by default and require `PYTHONUTF8=1` to be set for the tests to run already today (with or without the changes in this pull). Also, the CI and many other Bash scripts force UTF8 via `LC_ALL`. Finally, Python 3.15 will likely enable UTF8 on *all* systems by default, per https://peps.python.org/pep-0686/#abstract.
* So adding UTF8 to every single IO call is redundant, verbose, and confusing, given that it is the expected default.
So fix all issues, by:
* Removing the `test/lint/lint-python-utf8-encoding.py` check.
* Removing the encoding on the individual IO calls.
* Clarifying the existing docs around the existing UTF8 requirement and assumption.
Obviously, every IO call is still free to specify UTF8 or any other encoding explicitly, if there is a documented need for it in the future.
