simply running nsxiv with `--anti-alias` will enable anti-aliasing, and
running it with `--anti-alias=no` will disable it.
the cli flag will overwrite the config.h default.

* 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).

* link to online man-page
* rename: "N-R-K" -> "NRK"
* separate multiple links with a comma.
otherwise the links get messed up due to `[] []` being valid syntax for
reference style links with the 2nd `[]` serving as `id`.
* prefer codeberg links over github ones

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.

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.
