Neil Roberts 651a2775b5 poll: Add _cogl_poll_renderer_modify_fd
_cogl_poll_rendererer_modify_fd can be used internally to modify the
event mask on an FD to be polled. This will be used in the Wayland
backend to start blocking on write whenever flushing the display fills
the socket's buffer. Modifying the FD's events causes the poll age to
increase.
