Previously, the `references_of` implementation restricted the set of
references to certain categories: heads, tags, notes, rad, and cobs.
This is too restrictive to allow peers to share any references they
want. The only exceptions is references `refs/tmp/heads` that are
created for creating patches.
Previously, the remote helper would not support the `--force-with-lease` option.
This change introduces this support and ensures that it works as intended.

(i.e. an empty "root" comment), and also to change it later to a
non-empty string, however it was not possible to clear it again.
