[gtk/wip/matthiasc/popup5: 116/130] Get rid of GdkSurfaceImpl



commit a9e5428801014e1ac908926029b80bbb524173d0
Author: Matthias Clasen <mclasen redhat com>
Date:   Mon Apr 22 01:14:46 2019 +0000

    Get rid of GdkSurfaceImpl
    
    We don't need the complicated wrapper system anymore,
    since client-side windows are gone. This commit moves
    all the vfuncs to GtkSurfaceClass, and changes the
    backends to just derive their surface implementation
    from GdkSurface.
