(cherry picked from commit 10eec2ccb1)
Instead of getting the current msc value from the window, which might be
different to old one directly take the last saved msc value saved in
the window_priv struct.

In contrast to screen flip mode this mode:
* supports flips per windows (these windows currently need to have the same
size as their parent windows with the same pixmap),
* sends pixmap idle signals to the client only after the driver has given
an additional event notify.
This patch only introduces the new mode as a stub. It additionally needs a
driver hook, such that it can get initialized and appropriate cleanup
functions.
