Configure passed MaxActiveUDPPorts to xnet.StackConfig as a hardcoded 0 with "Unsupported as of yet", so no UDP socket could open and DNS and SNTP did not work, with no way to turn them on from LnetoConfig. lneto has supported UDP for a while: x/xnet's Socket handles "udp"/"udp4"/ "udp6" through udp.Conn and udp.PacketConn, and StackAsync exposes DialUDP and RegisterListenerUDP. Make the count a config field like MaxActiveTCPPorts, default 4.
