Internally the dns code has the ability to try connecting to multiple
addresses in a sequence. Expose this, as we'll want it for reconnection.

It was "connecting" to "localhost 30000" successfully, because it was
using UDP. Oops.
This reveals another issue: init_conn() uses the wrong address to
connect to, as we'd already incremented the pointer in try_connect_one().

Also based on pettycoin code.
(With embarrassing bug fixed where it didn't increment the address used,
thus using 100% CPU if that connect failed!)
