Mention REFUSED has the TC bit set with unmatched allow_cookie acl in the manpage (#1010)
* Mention REFUSED with TC with unmatched allow_cookie acl in manpage

Also moved the part about bypassing ip-ratelimit to the ip-ratelimit
description as it will be bypassed with a valid DNS-Cookie regardless of the
allow_cookie acl.

* Apply suggestions from code review

* Update doc/unbound.conf.5.in

* DNS-Cookies should bypass ip-ratelimit setting

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.

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.
