[PATCH v3 36/44] 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 backend internal functions
public. Later, we will use this to handle reflog updates for
per-worktree symbolic refs (HEAD).
