[Xastir] UDP frames

[Gerry Creager n5jxs]

The conventional wisdom on the APRS list is that UDP is evil, because 
Bob wants an ack from everyone.  Every time.  Never mind that APRS uses 
UI data to work.

Steve D. has supported him in the past.  I'm still working on him, but 
not real actively.

I expect the next generation of the IS will look more like multicast 
than connected unicast, but that's my opinion.

Would it work?  Sure.  Would it be as "reliable" as the connected 
version?  I suspect that statistically, it would be, but the occasional 
lost packet would be seized on a failure.
