onscreen: Add CoglFrameInfo and _add_frame_callback() api
Add a CoglFrameInfo object that tracks timing information for frames
that are drawn. We track a frame counter and frame timing information
for each CoglOnscreen. Internally a CoglFrameInfo is automatically
created for each frame, delimited by cogl_onscreen_swap_buffers() or
cogl_onscreen_swap_region() calls.
CoglFrameInfos are delivered to applications via frame event callbacks
that can be registered with a new cogl_onscreen_add_frame_callback()
api. Two initial event types (dispatched on all platforms) have been
defined; a _SYNC event used for throttling the frame rate of
applications and a _COMPLETE event used so signify the end of a frame.
Note: This new _add_frame_callback() api makes the
cogl_onscreen_add_swap_complete_callback() api redundant and so it
should be considered deprecated. Since the _add_swap_complete_callback()
api is still experimental api, we will be looking to quickly migrate
users to the new api so we can remove the old api.
