Since commit 3871f8be8d
("pulseaudioFull: fix wrapGApp wrapping"), the pulseaudio service files
have been referencing *unwrapped* binaries. This mostly hurts
pulseaudioFull, where using unwrapped binaries means there's no High
Fidelity A2DP profile at all. Plain pulseaudio (not -full) seems able to
use A2DP profile with SBC codec, but not aptX, as the latter requires
gstreamer / wrapper.
Since the wrapping of pulseaudio is a bit complicated (see referenced
commit), let's just fix the service files manually in preFixup.
Ref https://github.com/NixOS/nixpkgs/issues/203919.
Since
7a2605e0f3
the pulseaudio build recipe incorporates the `wrapGAppsHook`
wrapper setup-hook if `advancedBluetoothCodecs` are enabled.
This wrapper setup-hook -- like most wrappers --
wraps binaries in `$out/bin` by first renaming them,
then placing a wrapper script where the original binary was.
Unfortunatelly, pulseaudio doesn't like its
binary moved around after installation:
It records the binaries path during installation time
e5ad31e873/meson.build (L154)
then checks the path in `/proc/self/exe` and complains

if they don't match
e5ad31e873/src/daemon/main.c (L577)
Somehow, this also results in a real bug:
`pacmd` fails to connect to the pulseaudio server, see
https://github.com/NixOS/nixpkgs/issues/177915
To fix this issue, the commit at hand changes the
installation directory for binaries to `$out/.bin-unwrapped`.
After the installation, `$out/bin` is created by hand and
populated with symlinks to files in `$out/.bin-unwrapped`.
`wrapGAppsHook` doesn't know or care about the `.bin-unwrapped`
directory; it just sees all the symlinks in `bin`,
renames them and places wrapper scripts beside them.
Effectively, this leaves the original
binary in `.bin-unwrapped` unchanged!
So pulseaudio will find itself still in its oritinal place,
and "users" of the package can call pulseaudio
via the wrapper script in `bin` as usual.
The current postInstall removes all of $out/share, which also includes pulse's
vapi/deps files. Certain projects (budgie-desktop, for example) require these
definitions, but do not require the full pulseaudio server. Preserving these
files allows these projects to only depend on libpulseaudio.
Fixes#73463.
The x86_64 and aarch64 SDK attributes are named differently and don't
have the same contents. This was the motivation to try dropping the SDK
dependency altogether, relying only on the Libc and some frameworks.

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.
When cross-compiling, pulseaudio seems to not find some m4 macro
providing GSETTINGS_RULES.
However, apart from the obviously missing gsettings support, this works
just fine.
It only increases the closure size by 0.5M and users who do not set
the NixOS option `hardware.pulseaudio.package = pkgs.pulseaudioFull;`
will be stumped by their bluetooth audio not working.
