ddae1b4efa ci: remove gnu-getopt usage (fanquake)
Pull request description:
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.

Add a ci/lint.py script to run the linter both locally or inside the CI

Determines whether we are in a worktree, and mounts the real `.git`

fac5a1b10a test: Allow mempool_updatefromblock.py to run on 32-bit (MarcoFalke)
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 2123c94448), 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.

MSVCRT-related CI jobs should be removed from the CI framework once the migration to UCRT is complete.

Starting with Python 3.11, Pythons gzip might delegate to zlib.
Depending on the OS, i.e Ubuntu vs Fedora, the underlying zlib
implementation might differ, resulting in different output.
For now, or until a better solution exists, disable compression. This
results in the SDK increasing in size to ~157mb. Which is not
unreasonable, to regain determinism (and would be significantly worse
without the previous commit).

The encoding arg is confusing, because it is not applied consistently
for all IO.
Also, it is useless, as the majority of files are ASCII encoded, which
are fine to encode and decode with any mode.
Moreover, UTF-8 is already required for most scripts to work properly,
so setting the encoding twice is redundant.
So remove the encoding from most IO. It would be fine to remove from all
IO, however I kept it for two files:
* contrib/asmap/asmap-tool.py: This specifically looks for utf-8
encoding errors, so it makes sense to sepecify the utf-8 encoding
explicitly.
* test/functional/test_framework/test_node.py: Reading the debug log in
text mode specifically counts the utf-8 characters (not bytes), so it
makes sense to specify the utf-8 encoding explicitly.
The Bash script was acceptable, but CI_EXEC_CMD_PREFIX was a single
string, relying on brittle word splitting that the shellcheck SC2086
would warn about.
So just fix that by moving everything to the Python script and deleting
the Bash script.
This also removes the need to export the CI_CONTAINER_ID env var.
In theory one could run the CI without the rsync package installed, and
with DANGER_RUN_CI_ON_HOST=1. However, this seems to be an edge case.
Simply requiring rsync to be installed is less code and avoids brittle
edge cases around rsync failures.
It contains a large `bash -c` string, which is hard to parse. So pull
out components:
* CI_EXEC is only called with absolute folders as args, so the `cd` is
not needed in CI_EXEC. It is only needed to specify the working dir of
running the tests in 03_test_script.sh, so move it there.
* The PATH modification is only needed after commit
4756114e50 to check that depends does
work properly, even when the PATH contains a space.
* This allows to also drop the `bash -c` and use the proper and safer
"$@" to forward args without the risk of word splitting.
This move-only refactor clarifies that macos assumes and requires
DANGER_RUN_CI_ON_HOST.
So move the snippet under the condition for self-documenting code.
Can be reviewed with the git options:

The `retry` script is required for CI_RETRY_EXE and there are two ways
to put it into PATH:
* When running in a container engine, by copying it into /usr/bin
* When running without a container engine, by prepending its location to PATH
