[PATCH evdev 1/2] Don't pass superfluous arguments to EvdevPost*Events

[Éric Brunet]

The functions EvdevPostProximityEvents, EvdevPostRelativeMotionEvents,
EvdevPostAbsoluteMotionEvents and EvdevPostQueuedEvents are only called
by EvdevProcessSyncEvent. These functions take as arguments an array of
valuators which is set by EvdevProcessSyncEvent to contain ... nothing.
This patch changes the prototype of the four functions, their definitions
and the way they are called  to remove the useless array of valuators.
