gst/: add/move some code to handle wrapping/refcounting of possible

Browse source 
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
