        requestAnimationFrame callbacks should not fire within a modal dialog
        https://bugs.webkit.org/show_bug.cgi?id=53188

        requestAnimationFrame callbacks shouldn't fire while a modal dialog is up (like a window.alert()).
        This matches Firefox and other async APIs.  This patch moves the callback servicing into its own
        controller class which receives notifications on suspend/resume.
