The practical problem was also mitigated by libuv >= 1.32.0 (2ee2d46)

This part is fully compatible with 3.0, fortunately.
It was insufficient inclusion on our side anyway, working by accident.

Now those type definitions can be simply loaded without any error, e.g.
luajit daemon/lua/kres-gen.lua
That will be useful for checking them without regenerating them.

The test attempts to use the timestamp 2050-12-31T23:59:59, which can't
be represented with 32bit time_t due to Year 2038 problem.

Make sure we use the correct lemgth modifiers to support both 32b and
64b architectures.

Discovered case: TCP write towards upstream fails due to ECONNRESET,
and on this place of code we "forget" the whole qr_task and thus its
corresponding kr_request, so it remains unanswered and using memory.

The purpose of this change is to make it harder to accidentally use the
legacy DoH implementation and free up the "doh" kind which may be used
as an alias to a modern implementation in the future.

To (hopefully) improve readability, rename the typical macro usage of:

    if (!kr_assume(x)) y; // to
    if (kr_fails_assert(x)) y;

As a convenience, replace the assert without a return value to a more
simple version:

    (void)!kr_assume(x);  // becomes
    kr_assert(x);

Default 5 minutes (but off).
Randomize the delays +-25%.

- add lua options debugging.assumption_abort and
  debugging.assumption_fork to make the behaviour configurable
- select default values based on meson buildtype:
  - debug/debugoptimized (default, e.g. used in CI) - abort and don't
    fork
  - plain/release - don't abort, but fork if abort is user-configured
