I now checked in a different fix which checks windows for validity.  If
we still see bugs/crashes these should come from either of two sources:

(1) A not fully established frame.  In this case we should avoid calling
    the function from there as I did with the Fset_window_buffer calls.

(2) A dead frame.  In this case there's a bug in the frame deletion
    routine which should render any window on that frame invalid and
    it's that part that has to be fixed.
