DNS & IPv6

As you may have noticed I have been looking at the IPv6 support in the
last days, and now I am looking at how we perform DNS queries.

Today we first do an AAAA query, followed by an A query. As we anyway do
both queries it would be better if we ran both in parallell. The
benefits of this is twofold:

a) Lower latency.

b) Easier policy on re-transmission

But needs a bit of reshuffling to get done unfortunately, separating the
actual queries a bit from the lookup.

Henrik
