All hail Meson!
One serious issue is that building docs does not work.
We patch gobject-introspection to use absolute paths for shared libraries
in GIR files. Building the NetworkManager docs relies on the produced
introspection data but since the library is not yet installed
at the time the docs are generated, the build will fail.
It works in Autotools for some reason; they probably use
the pregenerated GIRs from the tarball.
Disabling the docs completely is not possible at the moment either,
since nmc [depends on them][1].
I have decided to fix this by pointing the installed location to the one
in the build directory using libredirect. Unfortunately, we cannot just set
the environment variables directly, since the build system runs
the documentation generator in a clean environment.
I have also added man, doc and devdoc outputs so the generated files have
somewhere to go.
Secondly, since Nix store is immutable, we also cannot use the package prefix
for configuration and mutable state data. At the same time, we cannot write
to the appropriate global directories during build. Autotools allowed to change
this in installFlags but Meson lacks similar mechanism so we need to patch
the build files.
Finally, I also removed the at_console patch since the permission has been
removed in 0.9.10.

Compatibility with other distributions/software and expectation
of users coming from other systems should have higher priority over consistency.
In particular this fixes#51375, where the NetworkManager-wait-online.service
broke as a result of this.
This fixes an issue I have faced when trying to connect to the internet
via wwan gsm modem.

Closes https://github.com/NixOS/nixpkgs/pull/19812
This reverts commit c25907d072.
I think this commit broke the NixOS service for NetworkManager. At least
with this, and the two previous reverts, everything is back to normal.
(With multiple-outputs split, it would have reduced the closure size by
3 MiB.)
NM upstream has a hardcoded path to /usr/bin/ping.
This patch changes:
- ping/ping6 are now from the nix store
- we no longer try to make substitutions on a missing file
- we use file from the nix store
