Upstream XMonad was using our xmonad patch file for their flake build to
support our nixos module. This would of course break the build upstream
if the version we patched and their master branch diverged. We
[discussed] that it'd make sense to upstream the environment var code.
In the process it seemed sensible to rename the NIX_GHC variable as
well, since it isn't really Nix-specific – it's just a way to set the
GHC binary to execute. This change has been [implemented] upstream in an
unreleased version of xmonad now – meaning we'll be able to drop the
xmonad patch soon!
This also clarifies the situation in nixpkgs a bit: NIX_GHC is easy to
confuse with the environment variable used in the ghcWithPackages
wrapper where it is used to set an alternative prefix for a GHC-wrapper
for applications trying to discover it via e.g. ghc-paths. It is an
implementation detail in this context, as it is in the case of the
xmonad module. Since they are different implementations doing different
things, different names also make sense.

Enabling soju without providing a value for tlsCertificate currently
results in:
error: The option `services.soju.tlsCertificate' is used but not
defined.
Since tlsCertificate is intended to be optional, set default to null.
Additionally, add assertions to ensure that both tlsCertificate and
tlsCertificateKey are either set or unset.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
Move the defaults to the `config` section of the module, and apply them
with mkDefault.
That way the defaults are merged with user-provided config, and are
merged without having to use lib.mkForce.
