GLib deprecated g_thread_init(), and threading support is initialized by GObject, so Clutter already runs with threading support enabled. We can drop the clutter_threads_init() call requirement, and initialize the Big Clutter Lock™ on clutter_init(). This reduces the things that have to be done when dealing with threads with Clutter, and the things that can possibly go wrong.
