[PATCH v5 24/26] refs: make files_log_ref_write functions public

[David Turner <dturner@twopensource.com>]

Because HEAD and stash are per-worktree, refs.c needs to go through
the files backend to write these refs.

In this patch, we make one files_log_ref_write public. Later, we will
use this to handle reflog updates for per-worktree symbolic refs
(HEAD).
