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.

749d1b9ebc - Expose if a query (or a subquery) was ratelimited (not src IP
ratelimiting) to libunbound under 'ub_result.was_ratelimited'.
  This also introduces a change to 'ub_event_callback_type' in
  libunbound/unbound-event.h.
- Tidy pylib tests.

7b948b0647 - Added generic EDNS code for registering known EDNS option codes,
bypassing the cache response stage and uniquifying mesh states. Four EDNS
  option lists were added to module_qstate (module_qstate.edns_opts_*) to
  store EDNS options from/to front/back side.
- Added two flags to module_qstate (no_cache_lookup, no_cache_store) that
  control the modules' cache interactions.
- Added code for registering inplace callback functions. The registered
  functions can be called just before replying with local data or Chaos,
  replying from cache, replying with SERVFAIL, replying with a resolved
  query, sending a query to a nameserver. The functions can inspect the
  available data and maybe change response/query related data (i.e. append
  EDNS options).
- Updated Python module for the above.
- Updated Python documentation.

031caba9c0 - and also generic edns options for upstream messages (and replies).
after parse use edns_opt_find(edns.opt_list, LDNS_EDNS_NSID),
  to insert use edns_opt_append(edns, region, code, len, bindata) on
  the opt_list passed to send_query, or in edns_opt_inplace_reply.
