Convert IPv4 multicast addresses to IPv6 multicast addresses in an IPv6 stack
-----------------------------------------------------------------------------

                 Key: JGRP-1189
                 URL: https://jira.jboss.org/jira/browse/JGRP-1189
             Project: JGroups
          Issue Type: Feature Request
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 2.10


When we run a config with mcast_addr="239.5.5.5" in an IPv6 stack, then the channel won't be created due to the sanity check exception.

Solution: map the IPv4 multicast address to an IPv6 equivalent, e.g.

239.5.5.5 --> FF0e::239.5.5.5, as outlined in [1]
