Instead of queuing the frame sync event immediately after a swap, the Wayland winsys now installs a frame callback and queues the event when Wayland reports that the frame is complete. It also reports the COGL_FRAME_EVENT_COMPLETE event at the same time because there is no more information we can give. This patch is a bit of a divergence from how the events are handled in the GLX winsys. Instead of installing its own idle function, the _cogl_onscreen_queue_event() function has now been made non-static so that it can be used by the Wayland winsys. The frame callback now just queues an event using that. The pending_frame_infos queue on the CoglOnscreen isn't used and instead the CoglFrameInfo is immediately popped off the queue so that it can be stored as part of the closure data when the frame callback is set up. That way it would use the right frame info even if somehow the Wayland callbacks were invoked in the wrong order and the code is a bit simpler.
