Merge branch 'bc/object-id'

Conversion from uchar[40] to struct object_id continues.

* bc/object-id:
  pretty: switch hard-coded constants to the_hash_algo
  sha1-file: convert constants to uses of the_hash_algo
  log-tree: switch GIT_SHA1_HEXSZ to the_hash_algo->hexsz
  diff: switch GIT_SHA1_HEXSZ to use the_hash_algo
  builtin/merge-recursive: make hash independent
  builtin/merge: switch to use the_hash_algo
  builtin/fmt-merge-msg: make hash independent
  builtin/update-index: simplify parsing of cacheinfo
  builtin/update-index: convert to using the_hash_algo
  refs/files-backend: use the_hash_algo for writing refs
  sha1-name: use the_hash_algo when parsing object names
  strbuf: allocate space with GIT_MAX_HEXSZ
  commit: express tree entry constants in terms of the_hash_algo
  hex: switch to using the_hash_algo
  tree-walk: replace hard-coded constants with the_hash_algo
  cache: update object ID functions for the_hash_algo
