Manually remove trailing white spaces
in `pkgs/**.nix` with the help of an editor
Auto-generated nix expressions containing trailing whitespaces:
* pkgs/development/haskell-modules/hackage-packages.nix
* See issue https://github.com/NixOS/cabal2nix/issues/208
* pkgs/**/eggs.nix
* I don't know how they are generated,
but they seems to be Python-related.
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.
Lots of packages are missing versions in their name. This adds them
where appropriate. These were found with this command:
$ nix-env -qa -f. | grep -v '\-[0-9A-Za-z.-_+]*$' | grep -v '^hook$'
See issue #41007.
