dix: Fix wrong cursor refcount.
Calloc cursor struct to ensure devPrivates are zeroed out and don't increase the refcnt for devices automatically when allocating a new cursor. Use new DeviceIsPointerType() to detect if device is a pointer _before_ device has been activated and can thus be identified and set up grab functions accordingly. This way we can increase the refcnt when we get a pointer grab.
