Fix GArray, GList, GSList, and GHashTable marshaling leaks

Remove calling of cleanup code for transfer-everything modes by ensuring
cleanup_data is set to NULL in from_py marshalers. Use array and hash
table ref/unref functions for container transfer mode to ensure we have a
valid container ref after invoke and during from_py cleanup of contents.
Rework restrictions with to_py marshaling cleanup so we always unref the
container for transfer-everything and transfer-container modes.
