This eliminates dereferencing freed window pointers when there is a
flip for that window in progress. The flip will complete, and then
immediately get undone (as we can't stop an in-progress flip).
Remove the vblank->window_destroyed field as we can signal this with
vblank->window == NULL instead.
Change check to vblank->window == NULL in:
present_flip_notify
Add check for vblank->window == NULL in:
present_vblank_notify
present_execute
present_flip_notify was also using vblank->window->drawable.pScreen,
so stop doing that and use vblank->screen instead.
