    clipboard: Drop now unnecessary code
    
    Before porting to GdkClipboard, and in order to get a clean diff,
    let's start by removing functions definitions which deal with the
    old GtkClipboard API and nothing specific with our custom content,
    as well as wrapper to get clipboard from a widget, which now is
    provided directly by GTK.
