W.C.A. Wijngaards 5eb362a6c0 - Fix that the aggressive negative cache does not insert NSEC 
records with overreaching next owner name. Also the result
  is not above the trust anchor's bailiwick. Also RRSIGS are
  not considered valid when an NSEC next owner name is not
  under the signer zone name. Thanks to Qifan Zhang, Palo
  Alto Networks, for the report.

  not considered valid when an NSEC3 is not b32.signerzone.

- Merge #1478 from petrvaganoff: pythonmod: add check return

Petr VaganovandGitHub 1bab2dfafa pythonmod: add check return value after ftell() (#1478)
