Merge branch 'ds/multi-pack-index'

Browse Source 
When there are too many packfiles in a repository (which is not
recommended), looking up an object in these would require
consulting many pack .idx files; a new mechanism to have a single
file that consolidates all of these .idx files is introduced.

* ds/multi-pack-index: (32 commits)
  pack-objects: consider packs in multi-pack-index
  midx: test a few commands that use get_all_packs
  treewide: use get_all_packs
  packfile: add all_packs list
  midx: fix bug that skips midx with alternates
  midx: stop reporting garbage
  midx: mark bad packed objects
  multi-pack-index: store local property
  multi-pack-index: provide more helpful usage info
  midx: clear midx on repack
  packfile: skip loading index if in multi-pack-index
  midx: prevent duplicate packfile loads
  midx: use midx in approximate_object_count
  midx: use existing midx when writing new one
  midx: use midx in abbreviation calculations
  midx: read objects from multi-pack-index
  config: create core.multiPackIndex setting
  midx: write object offsets
  midx: write object id fanout chunk
  midx: write object ids in a chunk
