socket_listen - attempt to make a TCP connection

       socket_listen  prepares  TCP  socket s to accept TCP connections.  It allows a backlog of approximately n
       TCP SYNs. (On systems supporting SYN cookies, the backlog is irrelevant.) Normally socket_listen  returns
       0.

       If anything goes wrong, socket_listen returns -1, setting errno appropriately.

         #include <libowfat/socket.h>

         int s;
         char ip[16];
         uint16 p;

         if ((s=socket_tcp6())==-1)
           strerr_die2sys(111,FATAL,"unable to create TCP socket: ");
         if (socket_bind6_reuse(s,(char *)V6any,8002,0) == -1)
           strerr_die2sys(111,FATAL,"unable to bind: ");
         if (socket_listen(s,1) == -1)
           strerr_die2sys(111,FATAL,"unable to listen: ");
