Original commit message from CVS: * gst/gst.defs: parse_launch also owns the return ref * gst/gstbin.override: fix a leak in get_by_name() * testsuite/common.py: loop when garbage collecting; necessary when deleting, say, a pipeline, that contains elements, to ensure the elements also get collected * testsuite/test_element.py: * testsuite/test_pipeline.py: test for garbage collection
