Replaced all remaining places that used it with explicit user specification. While doing this, I ran into stuff that was creating PendingIntent objects (that now need to specify the explicit user they are for), which are also posting notifications... but have no way to specify the user for the notification. So the notification manager in the system process now also gets a formal concept of a user associated with the notification, which is passed in to all the necessary aidl calls. I also removed the old deprecated aidl interface for posting/cancelling notifications, since we now always need a user supplied. There is more work that needs to be done here, though. For example I think we need to be able to specify USER_ALL for a notification that should be shown to all users (such as low storage or low battery). Along with that, the PendingIntent creation needs to be tweaked to be able to handle USER_CURRENT by evaluating the user at the point the pending intent is sent. That's for another change, however.
