1e0cf1e86b - Merge patch to fix for glue that is outside of zone, with
`harden-unverified-glue`, from Karthik Umashankar (Microsoft).
  Enabling this option protects the Unbound resolver against bad
  glue, that is unverified out of zone glue, by resolving them.
  It uses the records as last resort if there is no other working
  glue.

6cb75924d9 - Fix that DS queries with referral replies are answered straight
away, without a repeat query picking the DS from cache.
