Fixes a regression on Meson 0.57.0 that produces a timeout in config.ta_bootstrap test.

The double-free may have happened in some cases when the upstream
resolver was stopped while answering a forwarded query. I was reliably
reproducing it by running resperf on two kresd instances with one forwarded
to the other, and killing the upstream one.

The `check_uri()` function now only checks that the endpoint is either
`/doh` or `/dns-query`. Parameter checks were moved into
`process_uri_path()` so that the check only takes place for GET
requests. POST requests now do not care about parameters at all.

Though somehow I'm all the time getting false positives for
"daemon/bindings/impl.h"

It provides more information and the condition is typically
easier to read, too.

WARNING: You should add the boolean check kwarg to the run_command call.
         It currently defaults to false,
         but it will default to true in future releases of meson.

In almost all cases we already check the return code explicitly
and throw a more descriptive message than what would be the default.

The nghttp2 documentation states that we must not send data from inside
of its callbacks. It may result in crashes.

I was diffing logs from different runs and got annoyed by the shuffles.

I'm really sorry about this.  It's my regression in 5.5.0 (!1225)

Practical consequence was that the RW transaction was held open
until that instance did something with cache (and thus closed),
so any other instance would be frozen in the meantime if doing
anything non-read-only with cache (e.g. startup).

It's probably a bit more efficient, but this part of code should be
rarely used even on a resolver serving all in XDP.

Somehow I did this wrong when porting to libknot 3.1.

Also change the return type of kr_pkt_has_dnssec() and lua's :dobit()

This reverts commit 0c9ea133 (!1226).

CI rp:fwd-tls6.udp-asan now repeatedly shows use-after-free.
That could be a serious issue, and this commit's feature
seems less important than the risk.  Let's revert until the issue
gets deeper investigation.

The new limit is over 68 years, so still completely meaningless.
