d55084ea9e - Fix that if there are reply callbacks for the given rcode, those 
are called per reply and a new message created if that was modified
  by the call.
- Pass the comm_reply information to the inplace_cb_reply* functions
  during the mesh state and update the documentation on that.

Serve stale (#159) 
- Added serve-stale functionality as described in
  draft-ietf-dnsop-serve-stale-10. `serve-expired-*` options can be used
  to configure the behavior.
- Updated cachedb to honor `serve-expired-ttl`; Fixes #107.
- Renamed statistic `num.zero_ttl` to `num.expired` as expired replies
  come with a configurable TTL value (`serve-expired-reply-ttl`).
- Fixed stats when replying with cached, cname-aliased records.
- Added missing default values for redis cachedb backend.

0171d06aa2 - #4140: Expose repinfo (comm_reply) to the inplace_callbacks. This 
gives access to reply information for the client's communication
  point when the callback is called before the mesh state (modules).
  Changes to C and Python's inplace_callback signatures were also
  necessary.
