Merge branch 'sb/oid-object-info'

The codepath around object-info API has been taught to take the
repository object (which in turn tells the API which object store
the objects are to be located).

* sb/oid-object-info:
  cache.h: allow oid_object_info to handle arbitrary repositories
  packfile: add repository argument to cache_or_unpack_entry
  packfile: add repository argument to unpack_entry
  packfile: add repository argument to read_object
  packfile: add repository argument to packed_object_info
  packfile: add repository argument to packed_to_object_type
  packfile: add repository argument to retry_bad_packed_offset
  cache.h: add repository argument to oid_object_info
  cache.h: add repository argument to oid_object_info_extended
