Original commit message from CVS: * gst/gst.defs: * gst/gst-types.defs: Updated API * gst/gstelement.override: _wrap_gst_element_get_state: made wrapper behave more like codegen-ed functions. It now only takes an int or long as optional timeout argument, and if there's no argument it will use GST_CLOCK_TIME_NONE * testsuite/test_bin.py: * testsuite/test_event.py: * testsuite/test_ghostpad.py: * testsuite/test_pipeline.py: Updated testsuites for element.get_state() modifications Added event parsing checks Commented out test_ghostpad.PipeTest.testProbedLink til I find out why "while self._handoffs < 10: pass" doesn't exit although it reaches values way over 10
