e577ab105e stats: add counter for timed out queries 
Add counter `num_queries_timed_out` meaning queries that were sitting in the
socket queue and waiting to being processed too long. There is no reason
to process such queries, so let's drop it in the very beginning of the
pipeline.

preperly.

648ad4db6f Linting change. 
Remove config parser/lexer code as it's rebuilded every time but can
break adding new config options.
Also clean up the code base to avoid mixing actual code changes and lint
issues.

c7f44b99e3 Change file mode before changing file owner 
Change mode first when configuring remote control unix socket. Some
security systems might strip capability of changing other user's system
even to process with effective uid 0. That is done on Fedora by SELinux
policy and systemd for example. SELinux audit then shows errors, because
unbound tries modifying permissions of not own file. Fix just by mode
change as first step, make it owned by unbound:unbound user as the last
step only.

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.
