[PATCH 38/43] refs: make some files backend functions public

[David Turner <dturner@twopensource.com>]

Because HEAD and stash are per-worktree, other backends need to
go through the files backend to manage these refs and their reflogs.

To enable this, we make some files backend functions public.
