 Despite setting browser.cache.offline.enable to false, we still get
 prompted for allowing offline storage when sites try to use it. Canonical
 example: http://html5demos.com/offlineapp

 The prompt appears to be governed by browser.offline-apps.notify, which we
 don't set.

 I am pretty sure that this prompt runs through the permissions service,
 which we make memory only (#2950), but we should double check that through
 direct test.

 We should also bind both offline storage pref values to the "disk use"
 option from #3100.

 If we do tie the enabled state of this pref to the "disk leak" option, we
 should also verify it does not work from within
 frames/iframes/window.open().
