Merge branch 'bc/object-id'
Conversion from unsigned char [40] to struct object_id continues. * bc/object-id: Documentation: update and rename api-sha1-array.txt Rename sha1_array to oid_array Convert sha1_array_for_each_unique and for_each_abbrev to object_id Convert sha1_array_lookup to take struct object_id Convert remaining callers of sha1_array_lookup to object_id Make sha1_array_append take a struct object_id * sha1-array: convert internal storage for struct sha1_array to object_id builtin/pull: convert to struct object_id submodule: convert check_for_new_submodule_commits to object_id sha1_name: convert disambiguate_hint_fn to take object_id sha1_name: convert struct disambiguate_state to object_id test-sha1-array: convert most code to struct object_id parse-options-cb: convert sha1_array_append caller to struct object_id fsck: convert init_skiplist to struct object_id builtin/receive-pack: convert portions to struct object_id builtin/pull: convert portions to struct object_id builtin/diff: convert to struct object_id Convert GIT_SHA1_RAWSZ used for allocation to GIT_MAX_RAWSZ Convert GIT_SHA1_HEXSZ used for allocation to GIT_MAX_HEXSZ Define new hash-size constants for allocating memory
