More work on capsnego proxying. It should be OK now.
Original commit message from CVS: More work on capsnego proxying. It should be OK now. Added another testcase enum that shows various capsnego algorithms. Warn about pads that try to set a capability incompatible with their padtemplate. Implemented refcounting and copy_on_write for caps/props.
