parentpack-objects: refactor the packing list (diff)

pack-objects: factor out name_hash
As the pack-objects system grows beyond the single pack-objects.c file, more parts (like the soon-to-exist bitmap code) will need to compute hashes for matching deltas. Factor out name_hash to make it available to other files. Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
