[aprssig] APRS POST HTTP

[Robert Bruninga]

To answer the question in the link as to what established the packet
lengths in APRS, it is simple.
The 80 character line display in APRSdos.  Each packt type had some
abbreviated overhead as well, so the actual payload info was then limited
to what was left on the 80 character line.

Then came the Kenwood APRS radios.  And with tens of thousands of them out
there, then, sending packets longer than the standard gives tens of
thousands of users truncated displays and a breakdown in communications.

Besides, short packets in a collision based network have far better
probabilities of success.
