[Xastir] UDP frames

[Alan Crosswell]

PS: The reason for putting the callsign in the v6 address is not because we need 
an IP address (EUI-64 stateless autoconfiguration gets you a perfectly good 
address) but in order to meet(exceed) the FCC ID requirements by having every 
transmission contain the station callsign.
