socket_mchopcount6 - set multicast hop count

       socket_mchopcount6 sets the maximum hop count of outgoing multicast packets on the socket s.  Each router
       decrements  the  packet hop count by one and discards the packet if it reaches zero.  Setting the maximum
       hop count to 1, for example, will limit the packet propagation to the LAN.

       If something goes wrong, socket_mchopcount6 returns -1, setting errno appropriately.
