Add resolv.conf(5) option to force lookups by TCP: "options tcp"
Also Extend "nameserver" declaration syntax to support port
numbers. To avoid ambiguity these are only parsed when the address
is enclosed in square brackets, e.g. "nameserver [127.0.0.1]:5353"
Together these changes make forwarding DNS over a SSH tunnel very
easy, but unfortunately some programs in ports/ implement their
own resolvers (e.g. firefox). These will need to be modified to
support these options separately.
