For request_contents()/request_text(), the callback will be called
exactly once, so serves as its own destroy notifier callback.

set_with_data() has a destroy notifier callback:

 * @clear_func: when the clipboard contents are set again, this function will
 *              be called, and @get_func will not be subsequently called.
