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.
