I don't know any tool to do this offhand. But all the information is
in /var/lib/dpkg/status, so it's easy to do this with a script. The
attached Python script will print out the names of all the conffiles on
your system that have been changed or removed since they were installed.
If you are a non-root user, it also lists conffiles that you can't read;
on my system there are 7 of those.
Warning: my testing consisted of running it on my computer and
eyeballing the results to check that they made sense. If it breaks you
get to keep both pieces.
