3c87eb6c49 - harden-below-nxdomain: changed so that it activates when the 
cached nxdomain is dnssec secure.  This avoids backwards
         incompatibility because those old servers do not have dnssec.

78cc3d8ae1 harden-below-nxdomain option taken from draft-vixie-dnsext-resimprove. 
Default off (for now), as some older software that gives nxdomain for ENT
would be incompatible.  But that would only happen in the reverse tree, and
such software (nonDNSSEC) may go out of style, so in the future a default yes
could be possible.

498cc8ab88 - Change of timeout code. No more lost and backoff in blockage. 
At 12sec timeout (and at least 2x lost before) one probe per IP
  is allowed only.  At 120sec, the IP is blocked.  After 15min, a
  120sec entry has a single retry packet.
