def sort_gc_optimal(parent_map):

Sort and group the keys in parent_map into groupcompress order.

groupcompress is defined (currently) as reverse-topological order, grouped by the key prefix.

Returns A sorted-list of keys

def make_pack_factory(graph, delta, keylength, inconsistency_fatal=True):

Create a factory for creating a pack based groupcompress.

This is only functional enough to run interface tests, it doesn't try to provide a full pack environment.
