* peer_addr is now const * new_link_udp_server() can bind to address or INADDR_ANY * socket_udp_receive() happens without a loop * socket_udp_send() happens without a loop * sending in two packets (first size, then data) is only performed for TCP, SCTP, not for UDP anymore (it is unreliable, so we could miss something and will receive complete garbage)
