Merge branch 'jk/upload-pack-skip-hash-check'

The server side that responds to "git fetch" and "git clone" request has been optimized by allowing it to send objects in its object store without recomputing and validating the object names. * jk/upload-pack-skip-hash-check: t1060: check partial clone of misnamed blob parse_object(): check commit-graph when skip_hash set upload-pack: skip parse-object re-hashing of "want" objects parse_object(): allow skipping hash check
