Drop the public filtering API. The x11 backend already has the ::xevent signal as replacement. The win32 backend needs a similar signal to replace filtering. Reshuffle header inclusions in the x11 backend a little bit to avoid a cyclic inclusion between gdkprivate-x11.h and gdkdisplay-x11.h that is otherwise causing problems.
