    libXinerama: Set number of screens to 0 on error
    
    The documentation of XineramaQueryScreens states that number is always
    set to the amount of screens in the returned array, but if the
    communication with the X server fails, NULL is returned without
    modifying number.
    
    At least dwm relies on the fact that number is set to 0 on error, i.e.
    when NULL is returned. As a NULL pointer contains 0 elements and the
    documentation states that number contains the amount of elements of the
    returned array, I think this should be fixed inside libXinerama.
