BTW, compiling with --disable-libwacom raises 2 warnings:
evdev-tablet.c: In function 'tool_set_bits_from_libwacom':
evdev-tablet.c:652:1: warning: no return statement in function
returning non-void [-Wreturn-type]

but not used [-Wunused-function]

Actually, there are still some bumps here and there (not sure it worth
a v3, could be fixed later):
- the erasers of the artpen and the airbrush are declared as their
type, so even if libwacom correctly does not declare rotation and
slider, event-debug consider they have some (the copy bits is based on
the tools, not the capabilities)
- the wheel value of the mouse is rather weird: either +15, -15 and 0
(0 is reported whenever the wheel change value). I would have expected
that we count the actual absolute position of the wheel. But this is
what we currently have to the generic mice, so we might prefer to
stick to what we currently have.
Nothing to report on the rest of the devices once libwacom is fixed
locally and with the tablets not handled by libwacom.
Again, I'll try to review the patches one by one.
