Original commit message from CVS: * codegen/argtypes.py: Add handling of 'keep-refcount' for GBoxed arguments. * gst/gst.defs: Mark the appropriate 'gst_message_new_*' arguments when the method takes the ownership of the passed gst.Structure/gst.TagList * testsuite/test_message.py: Test for creating messages that take a gst.Structure/gst.TagList as argument and make sure they're properly created. Fixes #556054
