From: Michael Haggerty <mhagger@xxxxxxxxxxxx>
Add a new function add_packed_ref() that adds a reference directly to
the in-memory packed reference cache. This will be useful for
creating local references while cloning.

This new function call only stores the new reference to the in-memory
cache. The user has to remember to call pack_refs() to actually write
the new reference(s) to the packed-refs file. (I don't think it is
practical to make the write happen automatically.)
