This adds a _cogl_poll_renderer_add_idle api that can be used internally for queuing an idle callback without needing to make any assumption about the system mainloop that is being used. This is now used to avoid having the _cogl_poll_renderer_dispatch() directly check for all kinds of events to dispatch, and to avoid having the winsys dispatch vfuncs need to directly know about CoglContext. This means we can now avoid having a back reference from CoglRenderer to the CoglContext.
