Improve handling of vibration op, so that apps are better blamed (there is now a hidden vibrator API that supplies the app to blame, and the system now uses this when vibrating on behalf of an app). Add operation for retrieving neighboring cell information. Add a new op for calling a phone number. This required plumbing information about the launching package name through the activity manager, which required changing the internal startActivity class, which required hitting a ton of code that uses those internal APIs.
