Merge branch 'np/pack'
* np/pack: (27 commits) document --index-version for index-pack and pack-objects pack-objects: remove obsolete comments pack-objects: better check_object() performances add get_size_from_delta() pack-objects: make in_pack_header_size a variable of its own pack-objects: get rid of create_final_object_list() pack-objects: get rid of reuse_cached_pack pack-objects: clean up list sorting pack-objects: rework check_delta_limit usage pack-objects: equal objects in size should delta against newer objects pack-objects: optimize preferred base handling a bit clean up add_object_entry() tests for various pack index features use test-genrandom in tests instead of /dev/urandom simple random data generator for tests validate reused pack data with CRC when possible allow forcing index v2 and 64-bit offset treshold pack-redundant.c: learn about index v2 show-index.c: learn about index v2 sha1_file.c: learn about index version 2 ...
