gst/: Updated API

gst/: Updated API

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
