[Sugar-devel] Port from GStreamer Gst.Message.structure to get_structure()

[James Cameron]

GStreamer project removed or deprecated the structure field of Gst.Message, replacing it with a method get_structure().

Many activities are affected.

Code pattern to look for is a reference to message.structure, e.g.

	bus = pipe.get_bus()
	bus.connect('message', _cb)

	def _cb(bus, message):
	    message.structure. ...
