Rework wget, the xconnect interface, and its various clients

in order to fix the problems with round robin DNS reported
by Andrew Flegg:

This removes the ipv6 specific xconnect dns lookups.  I do
not see why that would need to be special cased for ipv6 as
was done, but that will just have to be tested.

So IPV6 people -- please test this change!
