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

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

* 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.
