gtk+3: Upgrade 3.18.8 -> 3.20.6

* Remove a patch that's no longer needed (as we don't
  have a problem with client side decorations anymore)
* Wayland build now depends on wayland-protocols:
  Use same WAYLAND_PROTOCOLS_SYSROOT_DIR trick as weston so
  protocols are found and multilib build does not break
* Add new binary gtk-query-settings to -dev package
* Rebase patches
* Modify 0003-Add-disable-opengl-configure-option.patch so
  that gdkx.h really is generated whenever it changes

* Depend on wayland-protocols in gtk+3-dev if Wayland is enabled as otherwise
  the pkg-config files can't be used - RB

+Subject: [PATCH 2/4] Do not try to initialize GL without libGL
+
+_gdk_x11_screen_update_visuals_for_gl() will end up calling epoxys
+GLX api which will exit() if libGL.so.1 is not present. We do not
+want that to happen and we don't want every app to have to set
+"GDK_GL=disabled" environment variable: so use #ifdef set based on
+opengl distro feature.
+
+Upstream is not interested in the fix as it is: Either epoxy should be
+fixed (to not exit) or GTK+ possibly could do some additional probing
+before calling epoxy APIs.
+
+Upstream-Status: Denied
