Merge change 4129 into donut
* changes:
Remove circular dependency in PackageManager. api freeStorage uses PendingIntent from android.app Create a new public IntentSender class that can be used by PackageManager instead. This new class uses IIntentSender internally and can only be created by PendingIntent for now. Provide a new getIntentSender api in PendingIntent to create an instance of this class. Move IIntentSender and IIntentReceiver from android.app to android.content Change imports of IIntentSender and IIntentReceiver to reflect the new package name The PackageManager api has been named as freeStorageWithIntent and will be renamed as freeStorage once the older api(which has been deprecated) will be removed shortly.
