The removed tip seemed especially misleading;
I don't think our root hints could've ever been used that way.
And latency to root servers has practically no impact on latency
of replies to reasonable answers (just like... once per day and TLD).

It looks like downloads won't work anymore:

 https://gitlab.nic.cz/knot/knot-resolver/-/jobs/890312
which is probably because long-term support ended last summer.

Adds just deckard!220

The changes are potentially too significant to do in a patch update.

- selection: utilize address_state::broken also when forwarding
- selection: drop fallbacks that don't make sense when forwarding
- iterate: copy EDE codes on DNSSEC SERVFAILs

Apparently it's never worked since its introduction.

.addr is non-nil exactly when .dst_addr is non-nil
(which hapens iff the query originated externally).
Now we have semantics which was probably intended by the original code
(98216295 from 2016) but that semantics is still problematic
if you need both kinds of matching in a single request from client.

This matching by destination has never made it to docs,
so let's just add this simple fixup for now, and later
we'll steer users to new policy configuration anyway.

I don't expect this matters, but why not fix this
to do what was intended (by the comment).

Fixes #781

We won't really support cygwin builds,
so I avoided saying the name and explaining details.

This reverts commit 0b9524b7.

The hack shouldn't be needed anymore:
https://github.com/Homebrew/homebrew-core/commit/4369052170f4360b7ad545f23b8a01a4ccb37683#diff-59a7902ada251dd9dba99b5bd323c1dba1d102d244ce766c06ce00097fb82e8fL71

This isn't an exact revert, but differences are minor.

Until now, kresd would refuse to start when a log_groups Lua call
contained a non-existent group. After this change, only a warning is
printed, which helps during development while switching between branches
with new logging groups. I don't think changing the configuration all
the time just for a logging group is warranted.

The debug dumps of packets used UNIX timestamps (in RRSIG validity)
instead of the customary human stamps.
This was an unintentional regression of 0555828e, i.e. since v5.4.1

I looked again at all other differences from default kdig style,
and the only ones are that we don't show class and don't do IDN.
(both seem suitable here)

Let's specify more of the dependencies explicitly.
I suspect it was pkg-config that was missing;

These packaging tests are dying anyway;
the manager branch reworked them.
So at least the breakages won't be shown in red until then.

Added the option to run `kresd` inside `pytests` under `valgrind` and
`rr`, which can help with debugging. Also added a clarifying note that I
personally would have liked to have while exploring this.

Since commit a0cbbde1 we don't ignore trailing bytes in queries.

They've been failing for many months, e.g. see

This way it at least won't be confusing by showing red in CI.

On most fundamental issues like DNS message not parsing,
we did not call this.  Selection needs such information.
