pr_usrreqs. Collapse duplicates with udp_usrreq.c and tcp_usrreq.c (calling the generic routines in uipc_socket2.c and in_pcb.c). Calling sockaddr()_ or peeraddr() on a detached socket now traps, rather than harmlessly returning an error; this should never happen. Allow the raw IP buffer sizes to be controlled via sysctl.
