[PATCH libevdev 2/2] Add a file to define missing bits for older kernels

[Peter Hutterer]

This is a very simple patch for now, adding more bits gets complicated
really quickly. So let's just add the most recent bits for now.

I've got a larger patchset that enables a lot more bits including RHEL6 support but
I think for now we should just enable the most recent additions. It gets complicated
really quickly otherwise and until we actually start shipping libevdev on RHEL6 we
don't need to worry about more.
