        Geolocation requests in progress when the frame is disconnected should invoke the error callback
        https://bugs.webkit.org/show_bug.cgi?id=43974

        If requests are ongoing when the Frame is disconnected, we abort them with a fatal error.
        To do this, when Geolocation::disconnectFrame() is called we call cancelAllRequests() to
        set a fatal error on all ongoing requests. Once the requests have made their error
        callbacks, they are deleted. Note that we check at callback time that the script
        execution context for the callback is still valid, so it's safe to attempt these
        callbacks even after the Geolocation object's Frame has gone.

        This requires a change to allow multiple calls to GeoNotifier::setFatalError().
        For repeated calls, we do not replace the existing error. This ensures that when
        permission has been denied and the frame is then disconnected, the error callback
        reports the permission error, as required by the spec.
