Merge branch 'cc/delta-islands'

Lift code from GitHub to restrict delta computation so that an
object that exists in one fork is not made into a delta against
another object that does not appear in the same forked repository.

* cc/delta-islands:
  pack-objects: move 'layer' into 'struct packing_data'
  pack-objects: move tree_depth into 'struct packing_data'
  t5320: tests for delta islands
  repack: add delta-islands support
  pack-objects: add delta-islands support
  pack-objects: refactor code into compute_layer_order()
  Add delta-islands.{c,h}
