cogl-queue: Make suitable for use in Cogl source code
This modifies cogl-queue.h so that:- - Everything is in a COGL_* namespace - It assumes there is a typedef for all of the types instead of requiring the code to use struct WhateverType. - It doesn't contain any tabs https://bugzilla.gnome.org/show_bug.cgi?id=652514
