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.

Cookie secret file (#1090) 
* - cookie-secret-file, define struct.

* - cookie-secret-file, add config option, create, read and delete struct.

* - cookie-secret-file, check cookie secrets for cookie validation.

* - cookie-secret-file, unbound-control add_cookie_secret, drop_cookie_secret,
  activate_cookie_secret and print_cookie_secrets.

* - cookie-secret-file, test and fix locks, renew writes a fresh cookie,
  staging cookies get a fresh cookie and spelling in error message.

* - cookie-secret-file, remove unused variable from cookie file unit test.

* Remove unshare and faketime dependencies for cookie_file test; documentation nits.

75f3fbdd65 Downstream DNS Cookies a la RFC7873 and RFC9018 
Create server cookies for clients that send client cookies.
Needs to be turned on in the config file with:

	answer-cookie: yes

A cookie-secret can be configured for anycast setups.
Also adds an access control list that will allow queries with
either a valid cookie or over a stateful transport.

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.

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.
