I chose not to do nixos.{config, options} because that would make it
look too much like a configuration object, which it is not.
A configuration object I would define as for example the result of
calling NixOS, an attrset with `_type = "configuration";`.
Recreating a configuration object without evalModules is quite
feasible but not guaranteed to be correct, and not maintainable.
Meson now comes with its own set of commands for building, testing,
installing etc., that by default wrap around Ninja. The reason to
prefer using the Meson commands is that they take additional
options (e.g. setting custom timeouts for tests — my motivation for
this change).
Here, I've modified the Meson setup hook so that Meson's test and
install commands will be used instead of Ninja's when Meson's
configurePhase is used. This restriction is to avoid starting to run
Meson directly when dealing with custom build systems that wrap around
Meson, like QEMU's. We don't use meson's compile command, as it just
runs ninja, and that's handled fine by the existing Ninja setup hook.
Naturally the Meson commands don't support entirely the same set of
options that the Ninja ones did, but I checked through Nixpkgs to find
any packages using Meson that used any options that wouldn't be picked
up by this new system. I only found one, and it was just setting
checkTarget = "test", which is the default value for Ninja and has no
Meson equivalent (because we directly tell Meson to run the tests
rather than going through a generic job system like Ninja).

This commit adds minimal documentation of the supported platforms.
More exhaustive documentation would require producing a list of
platforms for each of the 7 tiers. This was attempted in #245368, but it
quickly became clear that that would be a long-term effort.
In the meantime, this commit adds the most important information to the
manual.

The nixpkgs documentation mentions how to update out of tree plugins but
one problem is that it requires a nixpkgs clone.
This makes it more convenient.
I've had the need to generate vim plugins and lua overlays for other
projects unrelated to nix and this will make updates easier (aka just
run `nix run nixpkgs#vimPluginsUpdater -- --proc=1` or with the legacy commands:
`nix-shell -p vimPluginsUpdater --run vim-plugins-updater`.
I added an optional "nixpkgs" argument to command line parser, which is the path
towards a nixpkgs checkout. By default the current folder.

This change gets rid of the indirect reference to `nix-env -i` usage
and shows how to achieve the same goal with a shell expression.

The text was originally added [0] following an apparently incomplete
research on how everything plays together. In fact, Nix propagates
`outputs` to the corresponding nested derivations, and there is some
messy behavior in Nixpkgs that only seems to propagate
`meta.outputsToInstall` in `buildEnv`[1].
This change moves the hints on how to use NixOS specifics to NixOS
module documentation (which is hopefully easier to find through
search.nixos.org), describes the default behavior in Nixpkgs (updating
a the link to the source), and removes the confusing mention of
`nix-env`.
the last of them should not be there to begin with. we don't want
beginners to use `nix-env`, as this is known to run them into trouble
eventually.

>> 3: Discourage using package sets like python3.pkgs "directly"
> I think about 8 years ago I introduced this and it has been a clear mistake. Since then this pattern was copied throughout. We should indeed go to pythonPackages and also move the helpers such as buildEnv and withPackages into the package set, like haskell already had before.

Clarify that the monochrome font is not included, per #221181.
The new name is also coherent with the name of the font,
according to `fontconfig`: Noto Color Emoji.
This change which involves creating multiple outputs for CUDA
redistributable packages.
We use a script to find out, ahead of time, the outputs each redist
package provides. From that, we are able to create multiple outputs for
supported redist packages, allowing users to specify exactly which
components they require.
Beyond the script which finds outputs ahead of time, there is some custom
code involved in making this happen. For example, the way Nixpkgs
typically handles multiple outputs involves making `dev` the default
output when available, and adding `out` to `dev`'s
`propagatedBuildInputs`.
Instead, we make each output independent of the others. If a user wants
only to include the headers found in a redist package, they can do so by
choosing the `dev` output. If they want to include dynamic libraries,
they can do so by specifying the `lib` output, or `static` for static
libraries.
To avoid breakages, we continue to provide the `out` output, which
becomes the union of all other outputs, effectively making the split
outputs opt-in.
1. Clarify what is the reason for importing and to where it saves
2. Clarify that packages.sqlite is a temporary file
3. Link to section about native dependencies from first mention of ql.nix

Zig is still under active development, and new releases often introduce
breaking changes. This makes updating the default version of zig easier.
Some packages did not receive this change because they could be using
the c compiler or linker of zig, which doesn't receive as much breaking
changes compared to e.g. the zig std library.

This is very useful in conjunction with meta.pkgConfigModules, as the
new tester can use the list provided by this meta attribute as a default
value for moduleNames, making its usage in passthru.tests very
convenient.
For backwards compatibility, a shim under the old name is maintained
with a warning.
