The files configure.ac and version are already up to date.
Updated CHANGES with 9.17.0 release line.
Fixed CHANGES by adding GitLab reference to entry 5357 and fix
grammar mistakes.
Add missing /util/check-make-install.in to .gitattributes.
The lib/*/api are already updated to match the new ranges.
I listed two new features under BIND 9.17 features that to me
seemed noteworthy.
The release notes look good to me.
Convert the logic (currently present in the form of "rm -rf" calls in
util/kit.sh) for removing files and directories which are tracked by Git
but redundant in release tarballs into a set of .gitattributes rules
which allow the same effect to be achieved using "git archive".
