Add SRTT-based server selection system test 
Verify that the resolver selects authoritative servers in increasing
SRTT order.  Four servers are configured with increasing response
delays.  100 queries are sent, expecting most to go to the fastest
server (ns2).  Then ns2 stops responding, another 100 queries are
sent and should go to ns3 (the next fastest), and so on through
ns4 and ns5.  Each query uses a unique name to avoid cache hits.

ans{2-5} simulates four NS servers making authority on the same domain
`example.`. ans2 is the quickest to answer, followed by ans3, then ans4, with
ans5 being the slowest.
