Merge branch 'bc/object-id-part17'
Preparation for SHA-256 upgrade continues. * bc/object-id-part17: (26 commits) midx: switch to using the_hash_algo builtin/show-index: replace sha1_to_hex rerere: replace sha1_to_hex builtin/receive-pack: replace sha1_to_hex builtin/index-pack: replace sha1_to_hex packfile: replace sha1_to_hex wt-status: convert struct wt_status to object_id cache: remove null_sha1 builtin/worktree: switch null_sha1 to null_oid builtin/repack: write object IDs of the proper length pack-write: use hash_to_hex when writing checksums sequencer: convert to use the_hash_algo bisect: switch to using the_hash_algo sha1-lookup: switch hard-coded constants to the_hash_algo config: use the_hash_algo in abbrev comparison combine-diff: replace GIT_SHA1_HEXSZ with the_hash_algo bundle: switch to use the_hash_algo connected: switch GIT_SHA1_HEXSZ to the_hash_algo show-index: switch hard-coded constants to the_hash_algo blame: remove needless comparison with GIT_SHA1_HEXSZ ...
