Merge branch 'jk/dumb-http-finalize'

The dumb-http code regressed when the result of re-indexing a pack yielded an *.idx file that differs in content from the *.idx file it downloaded from the remote. This has been corrected by no longer relying on the *.idx file we got from the remote. * jk/dumb-http-finalize: packfile: use oidread() instead of hashcpy() to fill object_id packfile: use object_id in find_pack_entry_one() packfile: convert find_sha1_pack() to use object_id http-walker: use object_id instead of bare hash packfile: warn people away from parse_packed_git() packfile: drop sha1_pack_index_name() packfile: drop sha1_pack_name() packfile: drop has_pack_index() dumb-http: store downloaded pack idx as tempfile t5550: count fetches in "previously-fetched .idx" test midx: avoid duplicate packed_git entries
