[gtk+/wip/gtkmenutrackeritem-rebased: 1/6] action stuff: stop abusing GLib's namespace



commit 34270bb72de4e56cbc5feb1e58bb37a81fdf366e
Author: Ryan Lortie <desrt desrt ca>
Date:   Thu May 9 14:15:51 2013 -0400

    action stuff: stop abusing GLib's namespace
    
    Rename our internal GActionMuxer, GActionObserver and GActionObservable
    classes and interfaces to have names in our own namespace.
    
    These classes were originally intended for GIO but turned out to be too
    special-purpose to be useful there, so we never made them public API but
    have just been copying them around (without bothering to properly rename
    them).  Now that other people will be copying them out of Gtk, it's even
    more important to prevent this namespace abuse from spreading further.
