resolving NetBIOS names with a dot

uggh, what a name!

yeah, Samba chops names at the first . and uses that for the netbios
name. I realise now that this is a really bad idea but when I put that
in I didn't really imagine anyone would use names with a . in them.

There are a few places in samba where this assumption is made. Someone
needs to go through and clean it up then test with a large bunch of
test cases.

Any volunteers?

sounds sensible!
