[PATCH v3 0/8] Multiple simultaneously locked ref updates

Hi Folks,

Here is the third 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 and $gmane/233458.

Updates since the previous revision of the series:

* Incorporated style fixes suggested in patches 6-8.

* In patch 3, the local "lock" variables in update_ref_lock and
  update_ref now drop the existing "static" declaration.

* In patch 4, delete_ref_loose internals have been cleaned up
  as Michael suggested.

* In patch 6:

  - struct ref_update has been documented
  - update_refs now takes an array of pointers to struct ref_update
    as Michael and Junio both suggested
  - update_refs return cases were simplified with a label and goto
  - update_refs now stops immediately if any ref write fails
  - ref_update_compare now compares only the ref name

* In patch 7, another new input format is proposed.  It now uses
  quoting based on unquote_c_style.

* In patch 8, more new test cases have been added.  Failure cases
  are now covered in separate steps to simplify diagnosis.
