Refactor touchpad movement generation by migrating MovementMaker to userland.

This considerably overhauls touchpad event generation, simplifying and
cleaning it up considerably:

 * Return the touchpad specifications through the MS_IS_TOUCHPAD ioctl.

 * There is now a dedicated MS_READ_TOUCHPAD ioctl, as touchpads
   can either return touchpad_movement structures or mouse_movement
   ones depending on what mode they are operating in.

 * Event repeating on timeouts is now handled in MovementMaker and
   the input_server control thread, so MS_READ_TOUCHPAD takes
   a timeout value. This means we can drop all the EventProducers.

 * Use the real floating-point math functions in MovementMaker now
   that we are running in userland.

 * Drop unused structures, constants, headers, and other things
   related to touchpad support.
