Use a set of bitwise enum flags to set different keyboard accessibility features and the necessary vfunc hooks in clutter input device so that keyboard preferences can be passed to different input device implementations. The idea is to be able to configure either the clutter own implementation of keyboard accessibility for evdev, or eventually configure AccessX from the X11 clutter input device using the same mechanism. https://bugzilla.gnome.org/show_bug.cgi?id=788564
