This updates Wayland support in line with upstream changes to the Wayland API and protocol. This update means we no longer use the Cogl stub winsys so a lot of code that had to manually interact with EGL and implement a swap_buffers mechanism could be removed and instead we now depend on Cogl to handle those things for us. This update also adds an input device manager consistent with other clutter backends. Note: to use the client side "wayland" clutter backend you need to have built Cogl with --enable-wayland-egl-platform. If Cogl has been built with support for multiple winsys backends then you should run applications with COGL_RENDERER=EGL in the environment. Reviewed-by: Emmanuele Bassi <ebassi@linux.intel.com>
