Rather than relying on input-event-codes, define our own enum that is tailored
towards the tablet interface.

Because it's usually easier to pick holes into a patch proposal than come up
with ideas elsewhere, here's a quick-and-dirty patch.
Advantage: we control the button names/numbers and clients don't have to
know about cases where linux/input.h isn't enough.
Obvious drawback: adding new buttons requires a new protocol. Given this
hardware hasn't really changed much in quite a while, this may not be much
of an issue.
