converting protocol user requests to accept sockaddr instead of mbufs. remove tcp_input copy in to mbuf from sockaddr and just copy to sockaddr to make it possible for the transitional functions to go away. no version bump since these functions only existed for a short time and were commented as adapters (they appeared in 7.99.15).
