clang-tidy currently flags the following:
util.c:57:8: error: 'ptr' may be set to null if 'realloc' fails, which may result in a leak of the original buffer [bugprone-suspicious-realloc-usage,-warnings-as-errors]
ptr = realloc(ptr, size);
the analysis here is correct, but if realloc fails, we simply exit so
there's no real "leak".
moreover this check is not very useful for nsxiv's codebase because we
do not use naked realloc(), instead we use the erealloc wrapper that
exits on failure. so just disable the warning entirely instead of
changing the source code to silence the false positive.
this will be a massive change compared to the usual stuff. however the
gains will be worth it:
* we gain lots of additional animated image support.
* and we'll gain _even_ more format support as imlib2 adds them, without needing
any change in our code-base.
* about ~300 LoC will be purged once we remove our internal gif and webp loader.
as for when to remove the internal loaders, a good time might be when debian
upgrades their imlib2, currently it seems to be at v1.7.5, which doesn't support
animated images.
as of now, nsxiv will continue to build with the internal gif/webp loaders
(assuming they were enabled in config.mk) if imlib2 version is below 1.8.0 and
will print out a deprecation notice.
and if imlib2 version supports multi-frame then it will simply ignore the
internal loaders and use the imlib2 one.
in other words, users shouldn't need to do anything on their side. everything
that previously functioned will continue to function regardless of the user's
imlib2 version (though they might see the annoying deprecation notice if the
imlib2 version doesn't support multi-frame images).
known issue:
* image loading performance can be noticeably worse in
imlib2 versions below 1.9.0

opening a pull request if they wish.
also disables a noisy warning (bugprone-assignment-in-if-condition)
producing too many false positives.

* disable `cert-err33-c` and `readability-identifier-length` check
which causes warnings on clang-tidy v14.
* disable all "readability" checks by default, instead just opt-into the
useful ones (such as duplicate include).

This is mainly just to reduce the amount of files in the project root.
The criteria of what gets into `etc/` are the following:
* The file should not be necessary for building nsxiv. This excludes the
`icon/*` stuff since that's needed by `window.c`.
* The file shouldn't have any valid reason to stay in the project root.
This excludes things like `README.md`, `.gitignore` etc.
