Strongly inspired by the forgejo counterpart[1], for the following
reasons:
* The feature is broken with the current module and crashes on
authentication with the following stacktrace (with a PAM service
`gitea` added):

It only worked after turning off multiple sandbox settings and adding
`shadow` as supplementary group to `gitea.service`.
I'm not willing to maintain additional multiple sandbox settings for
different features, especially given that it was probably not used for
quite a long time:
* There was no PR or bugreport about sandboxing issues related to
PAM.
* Ever since the module exists, it used the user `gitea`, i.e. it had
never read-access to `/etc/shadow`.
* Upstream has it disabled by default[2].
If somebody really needs it, it can still be brought back by an overlay
updating `tags` accordingly and modifying the systemd service config.

This splits a dev output to make the default output not depend on any
build dependencies anymore. This also avoids removing references from
pgxs' Makefile this way, which should, at least theoretically, be good
to build extensions via pgxs, making sure they use the same tooling.
ecpg is the "embedded SQL C preprocessor", which is certainly a dev
tool.
Most important, for closure size anyway, is to move pg_config to the dev
output, since it retains paths to all the other outputs.
The only thing with references to the dev output remaining is then the
postgres binary itself. It contains all the output paths, because it
shows those in the pg_config system view. There is no other way than
to nuke those references to avoid circular dependencies between outputs
- and blowing up closure size again.
[UWSM](https://github.com/Vladimir-csp/uwsm) is a session manager that wraps a wayland
window compositor with useful systemd units like `graphical-session-pre.target`,
`graphical-session.target`, `xdg-desktop-autostart.target`.
This is useful for Wayland Compositors that do not start
these units on these own.
Example for Hyprland:
```nix
programs.hyprland.enable = true;
programs.uwsm.enable = true;
programs.uwsm.waylandCompositors = {
hyprland = {
compositorPrettyName = "Hyprland";
compositorComment = "Hyprland compositor managed by UWSM";
compositorBinPath = "/run/current-system/sw/bin/Hyprland";
};
};
```

This splits the 3rdparty drivers into seperate
packages as recommended by upstream. This also
allows to build a indi-full equivalent with only
the needed drivers. Also add indi-full-nonfree
with all the nonfree drivers. And remove them
from indi-full.

PAM support has to be enabled at compile time and upstream considers it
opt-in.
Official upstream binaries have it disabled.
We enabled it by default because we simply inherited most of it from
Gitea when the split in nixpkgs happened.
Reasons why it had been enabled in nixpkgs for Gitea are unknown.
See 9406f240a7.
There is reason to believe not a single Forgejo instance running on
NixOS uses this feature because it literally segfaults due to our
sandboxing.
