Move event polling into CoglRenderer

Browse Source 
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.
