Now it works again with the latest gdb-9.1.
As a side effect, some simplification was possible, so that some
typedefs are newly defined at once with the underlying type.

This new approach uses per-request variables in Lua and creates new
callback for each DEBUG_IF call instead of each request.

Attempt to avoid duplicating ten lines in debug_logfinish_cb lead me
to splitting kr_log_qverbose_impl into two functions kr_log_q and kr_log_req.
This is another minor change to API exposed to modules.

Formerly both logs used slightly different formats and duplicated code.
From now on verbose log and request tracing are generated using the same
code.

This required a small change to request trace_log_f definition so it
might affect external modules.

These files did not have GNU GPL v3 boilderplate in them so
I've added machine readable tag with appropriate license.

- written relatively defensively - act OK even if the API
  isn't used in an ideal way
- CI lint:scan-build: bump the error count;
  It's only another instance of the mis-detected array_push().
- the removed stale note in modules/meson.build isn't really related

The new way of transitioning to layer callbacks - done because of
portability (mainly to aarch64) - is a bit expensive.  This is a simple
way of recovering that cost.  Merge 603a24fc regressed speed a bit.

Somehow I didn't notice this field when adding ::add_selected.
We probably never put anything into answer's ADDITIONAL,
so noone's noticed a problem until now.

Also the log now uses the same format query UID format as elsewhere.

... without light userdata and yet it should be efficient.
Also with checkout layer, but I have no nice way of testing that one.

...when making calls from lua to C modules; use luaJIT FFI instead.
This eliminates some cases of lua_pushlightuserdata().

This will allow modules like view etc. work in the same way with packets
received over HTTP.

There is no reason to have two distinct functions to do the same task,
especially if the Lua version did not print all the information.
(Found and amended a bit by vcunat.)

All cache operations are now counted. These are internal cache
operations and do not map directly to number of queries or even number
of RRs.

Closes: !515

Function originally called kr_cache_sync() was in fact responsible
for calling mdb_txn_commit() and not mdb_env_sync() which was confusing.

and deduplicate the parsing logic.

It seems simpler, now that we have kr_rnd_buffered().

We use it as relatively high-level function, often on user-input names,
so it seems suitable that it does convert the case.
This fixes cache.clear('Example.Org.'), and probably also negative trust
anchors and policy uses.

When at it, switch to generating the libzscanner bindings.
