The output is only better if built with libknot >= 2.4.0.
As a side-effect, add lua method knot_rrset_t::txt_dump;
it's a light wrapper around knot_rrset_txt_dump.

Re-tested rolling with a.moot-servers.net, to be sure.

I believe it was unused, so no risk was caused, but better remove it.
There's the complication that its signature has changed since libknot-2.4.0.

These shouldn't make any problems:
- the verbose messages don't print any scope, and
- reputation cache doesn't consider scope.

Motivation: maintaining these by hand in kres.lua is tricky, as just
inserting or reordering the structures can do anything and isn't
detected in general.  For example, `rr_array_t::at` has always
"missed a star".

A couple libknot structure fields have apparently changed name since
the old definitions were written; in most cases I renamed them in *.lua.

The file daemon/lua/kres-gen.lua will be regenerated only if explicitly
deleted.  That requires building with debug symbols and gdb on $PATH.
