       - added get_all_metaclasses, get_all_metaclass_names
         and get_all_metaclass_instances method to allow
         access to all the cached metaclass objects.

+      - attribute slot initialization is now the responsibility
+        of the attribute itself, so we added a method for it
+        called initialize_instance_slot
