Stubs out _cogl_xlib_handle_event
This stubs out an xlib event handling mechanism for Cogl. The intention is for Clutter to use this to forward all x11 events to Cogl. As we move winsys functionality down into Cogl, Cogl will become responsible for handling a number of X events: ConfigureNotify events for onscreen framebuffers, swap events and Damage events for cogl_x11_texture_pixmap.
