ipcpd: Single UDP port for the ipcpd-udp0.18.0
The UDP layer will now use a single (configurable) UDP port, default
3435. This makes it easer to allocate flows as a client from behind a
NAT firewall without having to configure port forwarding rules. So
basically, from now on Ouroboros traffic is transported over a
bidirectional <src><port>:<dst><port> UDP tunnel. The reason for not
using/allowing different client/server ports is that it would require
reading from different sockets using select() or something similar,
but since we need the EID anyway (mgmt packets arrive on the same
server UDP port), there's not a lot of benefit in doing it. Now the
operation is similar to the ipcpd-eth, with the port somewhat
functioning as a "layer name", where in UDP, the Ethertype functions
as a "layer name".
