Move event polling into CoglRenderer 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.

Add api for queuing idle callback internally 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.

poll: Add general way to hook into mainloop without fd This adds a _cogl_poll_renderer_add_source() function that we can use within cogl to hook into the mainloop without necessarily having a file descriptor to poll. Since the intention is to use this to support polling for fence completions this also updates the CoglPollCheckCallback type to take a timeout pointer so sources can optionally update the timeout that will be passed to poll.

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.
