[glib/wip/glib-next: 16/27] Move the GThread implementations to glib/

[Ryan Lortie <ryanl src gnome org>]

commit 3345abb04d14a4dfe92a69d4b2d03245ebf429d9
Author: Ryan Lortie <desrt desrt ca>
Date:   Wed Aug 31 18:00:03 2011 -0400

    Move the GThread implementations to glib/
    
    We can now get threads initialised from inside of libglib by calling
    g_thread_init_glib().
