[Stefano Facchini <sfacchini src gnome org>]

commit 8fb361cb26bb1bea9d9f65c2856309ec95715791

    Add META_TAB_LIST_NORMAL_ALL to MetaTabList enum
    
    This is a new value, not associated with any keybindings, useful
    when the WM needs to order the applications by last-interaction,
    taking into account all windows.
