This updates the cogl_poll_ apis to allow dispatching events before we have a CoglContext and to also enables pollfd state to be changed in a more add-hoc way by different Cogl components by replacing the winsys->get_poll_info with _cogl_poll_renderer_add/remove_fd functions and a winsys->get_dispatch_timeout vfunc. One of the intentions here is that applications should be able to run their mainloop before creating a CoglContext to potentially get events relating to CoglOutputs.
