evdev-max-fixes.patch

gcc 4.3 warned:
evdev_axes.c: In function 'EvdevAxesRealSyn':
evdev_axes.c:170: warning: array subscript is above array bounds
evdev_axes.c:189: warning: array subscript is above array bounds

It uses axes[0x3f], which should be valid.

reviewing the code shows that XXX_MAX values are used a arraysizes, however
the arraysize should be XXX_MAX+1.

I fixed the array sizes and various checks to match reality better.
