[libgd/wip/rishi/main-box: 3/7] main-icon-view: Drop the priv pointer

[Debarshi Ray <debarshir src gnome org>]

commit bea8d6dca95bda36bf375a60cf10f79969a7ac1d

    main-icon-view: Drop the priv pointer
    
    The current GObject recommendation is to use the generated
    get_instance_private function instead of a separate priv pointer in the
    instance struct. The saves one pointer per class in the heirarchy
    multiplied by the number of instances of the type, and the function is
    fast enough because it only does pointer arithmetic.
