continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
* update two explicit references to jdk14 to just jdk, which no longer
points at jdk8 after #89731.
* patch an explicit -XX:+UseConcMarkSweepGC to -XX:UseG1GC, as the
former now throws an error (after having been deprecated since jdk 9)
After making `ffmpeg` point to the latest `ffmpeg_4`, all packages that
used `ffmpeg` without requiring a specific version now use ffmpeg_3
explicitly so they shouldn't change.
* some configure options have been removed upstream
* need a new patch to deal with gcc format warnings
11 remains, as it is an LTS release; all existing users of 11 in
nixpkgs remain on 11 for now.
openjdk/default.nix and openjdk/darwin/default.nix become the
expressions for the current version (12 now; later 13, 14, etc.).
(note: darwin/default.nix was unreferenced; the new version is derived
from darwin/11.nix.)
* increase heap size for building javadoc (this is only needed for the
32-bit build)
* filter out some non-maven jars that crop up in the openjfx build
