Still read, to not change byte stream offsets. Technically we could skip
those bytes, but this way it's clear for te future that we can use those
flags for anything needed.

Trim out any files we don't need downstream.
Automate doing the subtree merges, and automate resolving the
conflicts for updates for files that we want to have removed.
If updates end up with other conflicts, the script (or in practice,
git) exits without creating the intended merge commit - but
regular updates should run automatically.
Add a shell script that validates commit messages against FFmpeg
conventions. Based on the lint_commit_msg.py checker from mpv
(Kacper Michajłow, Timo Rothenpieler).
Supports three entry points: stdin (for CI pipelines), file
argument (for pre-commit commit-msg hook), and revision range
(for manual batch checking).
Checks enforced (errors block):
- Subject matches "component[/module]: description" pattern
- No conventional-commits style (feat:/fix:/chore:/refactor:)
- Blank line between subject and body
- No duplicate Signed-off-by from same person
- No multiple subject-like lines in body (squash-mess detection)
Checks that only warn:
- Subject line > 120 characters
- Trailing whitespace on subject line
- Subject should not end with a period
- Prefix should not contain file extension (.c, .h, etc.)
Merge, Revert and Reapply subjects are exempted from format checks.
Usage:
echo "avcodec/vvc: fix pred" | sh tools/check_commit_msg.sh
sh tools/check_commit_msg.sh .git/COMMIT_EDITMSG
sh tools/check_commit_msg.sh HEAD~5..HEAD

a valid RLE bitmap can decompress to far more than its input size, an early end-of-picture code
leaves the rest of the canvas blank, thus we cannot add a check in bmp decode

Failure to allocate a randomly sized buffer should not count as a anomaly in the fuzzer
there is nothing to fix in that case

When we try to lowercase register names (e.g. Q0 -> q0) we avoid
doing that for parts of the code that are comments, as comments
occasionally contain pseudocode that contain such mentions that
aren't register names, but pseudocode/reference code variables.
See 7ebb6c54eb for more details
about that.
In addition to recognizing comments starting with //, also
recognize /* and @ (which is a comment char in arm assembly, but
not in aarch64).
Match more SVE/SME specific details.
Also lowercase all register names. As this matches many cases
of code comments that refer to variables elsewhere, not specific
registers, we only apply this tranformation on the part of lines
before a potential comment.
This allows using the tool for one-off reindentations without needing
the check_arm_indent.sh script (e.g. for use outside of ffmpeg),
without having to pipe the file through stdin/stdout.
Before commit e96d90eed6 lavu/internal.h
contained redefined various discouraged/forbidden functions to induce
compilation failures upon use, like e.g.
#define malloc please_use_av_malloc
In order to use these functions, some files had to undefine these
macros. This commit removes the remaining pointless undefs.

The same also applies for arm assembly, but there are more known
deviations within that.
Add a script which checks all files, except for a few known files
that deviate, for various reasons.
Printing dummy logs during fuzzing can significantly slow the process
and blow the size of logs, making them both unredable and huge.
Keep the loggging commented-out for easy local restore if needed.
