[PATCH 34/43] refs-be-files.c: add method to rename refs

From
David Turner <dturner@twopensource.com>
Date

Message-ID
<1441245313-11907-35-git-send-email-dturner@twopensource.com>
In-Reply-To
<1441245313-11907-1-git-send-email-dturner@twopensource.com>

We also have to make rename_ref_available public, since alternate backends for rename_ref will need it.
