Merge branch 'jk/cleanup-object-parsing-and-fsck'
Crufty code and logic accumulated over time around the object parsing and low-level object access used in "git fsck" have been cleaned up. * jk/cleanup-object-parsing-and-fsck: (23 commits) fsck: accept an oid instead of a "struct tree" for fsck_tree() fsck: accept an oid instead of a "struct commit" for fsck_commit() fsck: accept an oid instead of a "struct tag" for fsck_tag() fsck: rename vague "oid" local variables fsck: don't require an object struct in verify_headers() fsck: don't require an object struct for fsck_ident() fsck: drop blob struct from fsck_finish() fsck: accept an oid instead of a "struct blob" for fsck_blob() fsck: don't require an object struct for report() fsck: only require an oid for skiplist functions fsck: only provide oid/type in fsck_error callback fsck: don't require object structs for display functions fsck: use oids rather than objects for object_name API fsck_describe_object(): build on our get_object_name() primitive fsck: unify object-name code fsck: require an actual buffer for non-blobs fsck: stop checking tag->tagged fsck: stop checking commit->parent counts fsck: stop checking commit->tree value commit, tag: don't set parsed bit for parse failures ...
