    completion: remove GtkSourceCompletionContainer
    
    This is unfortunate, but we cannot subclass GtkScrolledWindow anymore. We
    might bring this back, but more likely is that we'll reintroduce the
    sizing feature as part of a modernized completion API using newer GLib
    features such as GListModel.
    
    The fallout from this is tight control over the completion window height
    is temporarily lost until the new API lands.
