Stats for discard-timeout and wait-limit (#1159)

  instead of the mesh dropped that of requests exceeded.

Fix cache update when serve expired is used (#1143)
- Fix cache update when serve expired is used in order to not evict
  still usable expired records. Modules are forbidden to update the
  cache if their answer is DNSSEC unchecked or bogus and a valid
  (expired) entry already exists. Bogus replies from the validator are
  also discarded in favor of existing (expired) valid replies.

- serve-expired-ttl-reset should try to keep expired records in the
  cache in case they are reset.

d98c7b9ae3 - Implement cachedb-check-when-serve-expired: yes option, default
is enabled. When serve expired is enabled with cachedb, it first
  checks cachedb before serving the expired response.

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.

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.

f42d27e1a2 - Made new validator error string available from libunbound for
applications.  It is in result->why_bogus, a zero-terminated string.
	  unbound-host prints it by default if a result is bogus.
	  Also the errinf is public in module_qstate (for other modules).
	Binary API different. bumped library ABI version.
