Simon Thum ed9d58c3c2 dix: refactor pointer acceleration ...

The algorithm is split in a 2D-specific and a general part.
This potentially allows to accelerate more than just screen motion.
A state machine is intoduced to make code more explicit and readable.
It also improves handling of 'phase 1' mickeys when axial correction
kicks in (corner case).
