Merge branch 'bc/object-id'
The "unsigned char sha1[20]" to "struct object_id" conversion continues. Notable changes in this round includes that ce->sha1, i.e. the object name recorded in the cache_entry, turns into an object_id. It had merge conflicts with a few topics in flight (Christian's "apply.c split", Dscho's "cat-file --filters" and Jeff Hostetler's "status --porcelain-v2"). Extra sets of eyes double-checking for mismerges are highly appreciated. * bc/object-id: builtin/reset: convert to use struct object_id builtin/commit-tree: convert to struct object_id builtin/am: convert to struct object_id refs: add an update_ref_oid function. sha1_name: convert get_sha1_mb to struct object_id builtin/update-index: convert file to struct object_id notes: convert init_notes to use struct object_id builtin/rm: convert to use struct object_id builtin/blame: convert file to use struct object_id Convert read_mmblob to take struct object_id. notes-merge: convert struct notes_merge_pair to struct object_id builtin/checkout: convert some static functions to struct object_id streaming: make stream_blob_to_fd take struct object_id builtin: convert textconv_object to use struct object_id builtin/cat-file: convert some static functions to struct object_id builtin/cat-file: convert struct expand_data to use struct object_id builtin/log: convert some static functions to use struct object_id builtin/blame: convert struct origin to use struct object_id builtin/apply: convert static functions to struct object_id cache: convert struct cache_entry to use struct object_id
