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
