[PATCH v4 00/12] A bunch of object_id conversions

Thank you, everyone, for review and thanks, Junio for queueing two first patches - I removed them from v4, as there were no more comments to them anyway.

Compared to v3:

Patch 2 (formerly 4)
- renamed all parameter names sha1_stat to oid_stat
- renamed static function load sha1_stat to load_oid_stat
- adjusted a comment, that included "sha1_stat" in text

Patch 11 (formerly 13)
- fixed a typo in the commit message

Hopefully, this will be the last iteration on this batch of object_id conversions; I already have next batch prepared (I just need to clean it up before sending).

Patryk Obara (12):
  sha1_file: convert pretend_sha1_file to object_id
  dir: convert struct sha1_stat to use object_id
  sha1_file: convert hash_sha1_file to object_id
  cache: clear whole hash buffer with oidclr
  match-trees: convert splice_tree to object_id
  commit: convert commit_tree* to object_id
  notes: convert combine_notes_* to object_id
  notes: convert write_notes_tree to object_id
  sha1_file: convert write_sha1_file to object_id
  sha1_file: convert force_object_loose to object_id
  sha1_file: convert write_loose_object to object_id
  sha1_file: rename hash_sha1_file_literally
