Original commit message from CVS: * gst/Makefile.am: * gst/common.h: * gst/pygstobject.c: (pygstobject_sink), (pygstobject_new), (pygst_object_unref): * gst/pygstobject.h: * gst/gstmodule.c: (init_gst): add/move some code to handle wrapping/refcounting of possible GstObject * codegen/argtypes.py: * gst/gstbin.override: * gst/gstbus.override: * gst/gstelement.override: * gst/gstpad.override: * gst/interfaces.override: use this reffing code * gst/gst-types.defs: * gst/gst.override: add a __gstrefcount__ field to GstObject types add tp_traverse, tp_dealloc and tp_clear, so we handle refcounting properly related to garbage collection * testsuite/test_element.py: * testsuite/test_pad.py: add more tests, add some refcount checks
