[PATCH 00/26] object_id part 17

This is the seventeenth and final object_id series. The patches mostly switch sha1_to_hex to hash_to_hex, remove null_sha1 in favor of null_oid, and replace some hard-coded constants (along with GIT_SHA1_HEXSZ) to use the_hash_algo.

This series may downloaded from the normal places as "object-id-part17".

Additional patches for test fixes will be required, but beyond that, the next series of actual code changes will involve introducing the `extensions.objectFormat` flag and the ability to create repositories and run the testsuite with SHA-256. A preview of this work may be seen in the "transition-stage-4" branch.
