Multihash Implementation for Glance
Adds the ability to compute a "multihash" (see the Glance spec
for what this is exactly). To maintain backward compatability,
a new store_add_to_backend_with_multihash function is added.
Backward compatability for each store's add() method is achieved
by a back_compat_add wrapper.
