[PATCH 00/16] Convert parts of refs.c to struct object_id

This is part 1 of n in converting code to use struct object_id.

refs.c, and the for_each_ref series of functions particularly, is the source for many instances of object IDs in the codebase. Therefore, it makes sense to convert this series of functions to provide a basis for further conversions.

This series is essentially just for_each_ref and friends, the callbacks, and callers. Other parts of refs.c will be converted in a later series, so as to keep the number of patches to a reasonable size.

There should be no functional change from this patch series.

This series is based on top of the bc/object-id series in pu. The series will be rebased on next once bc/object-id makes it into next.

Available from the following repositories in either object-id-part1 or object-id-part1-pu (will be rebased):
