Make more things internal to this file.  Remove visit_finalizer_reachable since it's the same as visit_reachable. Rename visit_reachable to visit_move.  Objects can now have the GC type flag set, reachable by tp_traverse and not be in a GC linked list.  This should make the collector more robust and easier to use by extension module writers.  Add memory management functions for container objects (new, del, resize).
