Calculate touch data for semi-mt devices, but don't send touch events
Previously, all touch data from semi-mt devices was ignored because the
X server doesn't support them. However, the touch data must be used for
proper clickpad handling.
Instead of ignoring semi-mt device touch events, mark the device as
being semi-mt and allow initialization of the touch state. The touches
will then be used in calculating the cumulative_d{x,y} values that are
needed for clickpad support.
When handling the touch data for X event processing, simply skip over
reporting the touches.
