Add a new generic helper function gst_vaapi_window_new() to create a window without having the caller to check for the display type himself. i.e. internally, there is now a GstVaapiDisplayClass hook to create windows, and the actual backend implementation fills it in. Add new generic helper functions gst_vaapi_texture_new_wrapped() This is a simplification in view to supporting EGL.
