WindowServer: Implement mechanism to restore safe mode setting

Browse source 
Such mechanism will be used by the Intel Graphics driver, because we
lack support of changing the resolution on this driver currently, so,
when WindowServer will try to mode-set the display then it will fail,
and will use the safe mode-setting call instead to be able to show
something on screen.
