Conform to dns_adb_createfind() API changes.

If we're looking up the address of a nameserver who's name is a
...
subdomain of the query domain, tell the ADB to start looking at "." if
it doesn't know the address. This keeps us from getting stuck if the
nameserver is beneath the zone cut and we don't know its address
(e.g. because the A record has expired). By restarting from ".", we
ensure that any missing glue will be reestablished.

Cancelation of TCP queries while they were still connecting was broken, and
...
would cause seg faults.
Do not update the RTT if a query is being canceled due to internal failures.
Some servers generate badly formatted responses when they get an EDNS
query. We were marking these servers as bad, but a more practical
solution is to retry without EDNS. If a message fails to parse due to
DNS_R_FORMERR or DNS_R_UNEXPECTEDEND, and we were using EDNS, we now
retry the query without EDNS.
Add a "default" case to the message parsing error switch. This prevents bad
things from happening if message parsing fails in a nontypical way.
