[PATCH 10/11] ipc: clear the payload when moving a receive port

Clear the protected payload when a receive port is moved from one ipc space to another. This is done to retain the old behavior of mach_msg, so that a port name is sent in the msgh_local_port field. If the new owner of that receive right wishes to use the protected payload mechanism, it has to be
