* switch to git ls-files to avoid picking up any other local .c files
* enable assertions during static analysis since we used some assertions to
disable/silence certain warnings.
* update TCC commit hash to a more recent one
* parallelize static analysis
cppcheck already has -j argument to parallelize it's analysis and
provide results faster, clang-tidy unfortunately doesn't.
so use xargs -P to archive parallel execution. on my system this brings
down the analysis time from ~27s to ~5s.
the fedora copr repo is no longer being updated since the maintainer of
it, mamg22, no longer uses nsxiv in his daily setup (and thus stopped
contributing to nsxiv as well).
he has requested the repo and his email to be removed from the project.
so go ahead and honor that request.
also take this as an opportunity to remove some long inactive
maintainers from the CURRENT MAINTAINERS section of the manpage.

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.
The last time[0] this was discussed, no-one was against it but no-one
was confident in it either and so it was added to nsxiv-extra as a
patch.
But now that enough time has passed, it seems like there's a pretty high
demand for something like this because there's plenty of use-cases that
use nsxiv as a "picker" where it's meant to quickly pick a single file.
And so add this as a convenient default key-bind.

removes a couple maintainers who have never been active in the
development.
there are a couple other maintainers have not been active in a while,
but was somewhat active in the past. so keep their names in it
(for now at least).
also re-arrange the entires a bit based on activity.
this section was added almost 10 years ago (see commit 60f84190f) back
when sxiv was pretty new and didn't have many contributors.
the situation has obviously changed now, especially with `nsxiv` we have
a fair amount of contributors now. so it makes no sense to special case
a couple of them.
now that we have long-opts, we don't have to worry about exhausting the
alphabet list for short-opts. so adding a cli flag to set/unset the
checker background makes sense.

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

* Imlib2 supports modifying gamma, brightness and contrast directly
while sxiv only supports gamma. Makes sense to extend it to brightness
and contrast as well.
* Since color corrections need to be aware of each other, they have been
refactored into one centralized function.
* This also makes the code more hackable as it makes it easier to add
more color correction functions without them interfering with each
other.

Uses [optparse] to add support for long-opts. optparse is posix
compliant with getopt(3) and thus would be backwards compatible.
It does not have any dependency (not even the c standard library!) and
is C89 compatible and thus fits our current code-style.
[optparse]: https://github.com/skeeto/optparse
Note that we're using a couple `pragma`-s to silence some harmless
warnings. This should be portable because these pragma-s don't change the
behavior of the program. Furthermore, C standard mandates that unknown
pragma's should be ignored by the compiler and thus would not result in
build failure on compilers which do not recognize them.

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.
