mixing signed and unsigned types in comparison can end up having
unintended results. for example:
if (-1 < 1U)
printf("true\n");
else
printf("false\n");
previously we silenced these warnings, instead just fix them properly
via necessary casting, and in cases where the value cannot be negative
(e.g width/height members) make them unsigned.

- apt-get is slow, takes up ~1m40s just to install deps, fix it by not
using it. instead use alpine linux for codeberg ci, which brings build
time down to 25s.
- And since alpine uses musl, it's probably a good idea to use it on our
ci since it might catch us using any glibc extensions. The github ci
can keep using ubuntu.
- remove duplication of CFLAGS by having it on a separate file instead.
- remove pull_request from github ci since we no longer accept PRs
there.
