add codeberg ci and cleanup github one (#311) - 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.

fix: -Wsign-compare warnings (#336) 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.
