Upgrade to version 9.7.1-P1. The patch addresses 2 areas in the resolver
code where the 9.7.x series tightened its adherence to the DNS protocol
as written, vs. the 9.6.x series which was more liberal in what it accepted.

Specifically:
1. Restore processing of certain forms of negative responses that do
   not contain all of the required elements to avoid aggressive
   re-querying of authority servers.
2. Accept answers from authority servers without the AA bit set
   if they meet the other requirements of an answer packet.
