pennae 2e751c0772 treewide: automatically md-convert option descriptions
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.

Enable Git daemon, which allows public hosting of git repositories
without any access controls. This is mostly intended for read-only access.
You can allow write access by setting daemon.receivepack configuration
item of the repository to true. This is solely meant for a closed LAN setting
where everybody is friendly.
If you need any access controls, use something else.

Remap all the path requests as relative to the given path. For example,
if you set base-path to /srv/git, then if you later try to pull
git://example.com/hello.git, Git daemon will interpret the path as /srv/git/hello.git.

Publish all directories that look like Git repositories (have the objects
and refs subdirectories), even if they do not have the git-daemon-export-ok file.
If disabled, you need to touch .git/git-daemon-export-ok in each repository
you want the daemon to publish.
Warning: enabling this without a repository whitelist or basePath
publishes every git repository you have.
