I'm also really not sure if this is correct, or what scenario it even fixes.
The vast majority of uses of UDP are strictly unidirectional, making 
this a non-issue.

DTLS is one of the few exceptions there, and as the user of udp.c should 
be the one responsible for setting the appropriate destination address 
when in "server" mode.
