It seems better to check RRSIGs before checking negative proofs,
in terms of reasoning, being less error-prone, etc.

selection: cap the timeout value when probing a random server
This patch caps the timeout set on UDP queries to servers chosen in the
EXPLORE phase of the selection algorithm to two times the timeout that
would be set if we were EXPLOITing.
This measns that we no longer spend an unreasonable amount of time
probing servers that are probably dead anyway while ensuring that we do
probe them from time to time to check if they didn't come to life.
If the timeout value is capped and the server fails to respond, we don't
punish the server for it i.e. we don't cache the timeout.

utils/cache_gc: fix crashes/assertions on RTT entries
I missed some parts when finishing this. I should've tested it better.
GC would hit assertions or NULL dereferences when removing entries,
and eventually that would lead to cache overflowing (and getting
cleared).

dnstap: don't break request resolution on dnstap errors
This isn't a regression of 5.3.0 changes.
Layer functions are supposed to return new values for ctx->state,
but here we were sometimes returning kr_error(EFOO) which altered
processing of the request.
Our case: answers directly from policy module would not end up
finishing the request and we'd hit an assert at the end of processing.

lib/selection{,_iter}.c: allow switching back to UDP
Switching to TCP instead of querying very slow servers over UDP has had
unwanted side effect – we would sometimes get stuck with a server
permanently switched to TCP. And if the server happens to not reply over
TCP we were in trouble.
Therefore after we TCP connect fails or timeouts we provide one last
chance for the server over UDP. This will not prevent the next request
to try TCP again on this server again, but we don't care because
DNS MUST ******* work over TCP.

modules/{http,watchdog}: fix stability problems
As first noted in commit d1a229ae9, in some cases we do call chains that
are not supported for JIT in LuaJIT.
I'm not 100% sure all of these are needed to comply, but the functions
here are really small and probably not to be that heavily used,
so I don't think it will be costly to interpret them
(and avoiding crashes is more important).
In my tests this fixed occasional crashes when using http://*/trace/*

Merge !1130: when FORMERR comes, differentiate based on OPT
commit 2cdd2d234183ad1050e3e00559fc700a0435e8be
Author: Vladimír Čunát <vladimir.cunat@nic.cz>
Date: Mon Feb 1 10:09:16 2021 +0100
when FORMERR comes, differentiate based on OPT
In particular, non-support of EDNS is implied iff FORMERR without OPT
comes. If OPT is there, one possibility is that there was something
wrong in the OPT that *we* sent, but it seems much more likely that
this particular server is just bad and we want to try another one.
https://tools.ietf.org/html/rfc6891#section-7
In particular, we would be in trouble if we dropped OPT in a zone
that is covered by DNSSEC.

Lame delegations are weird, they breed more lame delegations on broken
