socket_broadcast - set UDP socket to broadcast mode

       socket_broadcast  sets  UDP  socket s to broadcast mode.  socket_send4 and socket_send6 will fail to send
       packets to the broadcast address unless socket_broadcast is called before.

       Normally socket_broadcast returns 0.

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

         #include <libowfat/socket.h>

         int s;

         if ((s=socket_udp6())==-1)
           strerr_die2sys(111,FATAL,"unable to create UDP socket: ");
         if (socket_broadcast(s) == -1)
           strerr_die2sys(111,FATAL,"unable to set broadcast mode: ");
