[PATCH v2 00/12] Improve "refs" module encapsulation

This is v2 of this patch series. I think I have addressed all of the
feedback from v1 [1]. Thanks to Stefan, Peff and Junio for their
feedback.

Changes since v1:

* Change docstring for delete_ref() and a comment within the function
  definition.

* Squash together two commits dealing with the error message in
  delete_refs().

These patches are also available from my GitHub account [2] as branch
"init-delete-refs-api".
