[PATCH v6 0/8] Multiple simultaneously locked ref updates

Hi Folks,

Here is the sixth revision of a series to support locking multiple refs at the same time to update all of them consistently. The previous revisions of the series can be found at $gmane/233260, $gmane/233458, $gmane/233647, $gmane/233840, and $gmane/234324.

Updates since the previous revision of the series:

* The entire series was rebased on master at bb80ee09; it was
  previously based on v1.8.4.

* A conflict in refs.c with 47a59185 was resolved by preserving
  the elimination of find_ref_by_name while adding our new content.

* A conflict in builtin/update-ref.c with d5d09d47 (Replace deprecated
  OPT_BOOLEAN by OPT_BOOL, 2013-08-03) was resolved by integrating
  both changes.  The new options added in patch 7 now use OPT_BOOL.
