Things to work on for debian packaging for knot-resolver:

* clean up javascript bundled by upstream, try to regenerate it from source

* write a more complex autopkgtest test suite

* clean up ahocorasick.so build
   (modules/policy/lua-aho-corasick/Makefile does not appear to use
   CPPFLAGS or LDFLAGS from the environment).  This would hopefully
   address hardening-no-bindnow usr/lib/knot-resolver/ahocorasick.so

* address all the warnings about ISO C and C99

* trim linker dependencies.  lots of "(they use none of the library's
   symbols)" warnings.

* nudge upstream toward multi-arch

* (autopkgtest): ensure that libkres-dev is actually usable by another
   project, and not limited only to kresd.

* can we drop python3 from build-depends and leave it only in
   build-depends-indep?
