Silvan Mosberger 4f0dadbf38 treewide: format all inactive Nix files
After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.

Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.

A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

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

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.
