Subject: This is a large patch (sorry). Migrate from struct in_addr to struct
 sockaddr_storage in most places that matter (ie. not the nmbd and NetBIOS
 lookups). This passes make test on an IPv4 box, but I'll have to do more
 work/testing on IPv6 enabled boxes. This should now give us a framework for
 testing and finishing the IPv6 migration. It's at the state where someone
 with a working IPv6 setup should (theorecically) be able to type : smbclient
 //ipv6-address/share and have it work. Jeremy. (This used to be commit
 98e154c3125d5732c37a72d74b0eb5cd7b6155fd)
