[PATCH weston] input: add a weston_pointer_clear_focus() helper function

This adds a function to clear pointer focus and also set the sx,sy
co-ordinates to an arbitrary value we shouldn't compute with.
Assertions are added to make sure any time pointer focus is set to NULL
these values are used.
weston_compositor_pick_view() now returns these values too.

Ok, so I didn't do quite what I set out to, but I think this is better :)
Pekka, does this roughly cover what we talked about? Now everyone sets sx,
sx "properly".
Not sure how I feel about the previous patch. I think it's superfluous now,
as the pointer co-ordinates test should fail and stop the focus signal from
firing.
