f82a0847eb - max sent count. EDNS1480 only for rtt < 5000. No promiscuous 
fetch if sentcount > 3, stop query if sentcount > 16.  Count is
reset when referral or CNAME happens.  This makes unbound better
at managing large NS sets, they are explored when there is continued
interest (in the form of queries).

d56aef7b33 - Fix validation failures due to EDNS backoff retries, the retry 
for fetch of data has want_dnssec because the iter_indicate_dnssec
         function returns true when validation failure retry happens, and
         then the serviced query code does not fallback to noEDNS, even if
         the cache says it has this.  This helps for DLV deployment when
         the DNSSEC status is not known for sure before the lookup concludes.

firewalls), but also not probed all the time (because of the request
