This is a rather large patchset because it involved quite a fair bit of
revamp of things. The actual interesting bits are just in the last patch,
the rest moves code like a specific member of the rolling stones.

The wacom tablet transducers aren't as accurate as a perfect world would
require them to be, so using the libinput driver as tablet driver (the
long-term goal) leads to little dents in the lines. The wacom driver fixes
that by averaging the last 4 coordinate values so rather than being creative
about that we do the same. It just took a bit of rework to slot that in

The tests needed to be updated as well, most of those are just ensuring we
have enough events in the pipe to negate the averaging effect.
