Throttle the rate of UDP_INFO messages.

Browse source 
This makes sure UDP_INFO messages are only sent at the maximum rate of
5 per second (by default). As usual with these "probe" mechanisms, the
rate of these messages cannot be higher than the rate of data packets
themselves, since they are sent from the RX path.
