* changes:
For intent ACTION_PACKAGE_CHANGED, there could be a lot of broadcasts related to enabling/disabling components by apps which could result in thrashing on the PackageManager. For apps that do not want to be restarted when such a broadcast is sent, we can just aggregate these broadcasts and handle them at one go. Changes include: New structure to hold pending broadcasts by class name. If a component is enabled or disabled frequently aggregate component enabled/disabled settings in this structure in a 10 second window and then send out the accumulated list of broadcasts to the ActivityManager. A new Handler implementation handles this message Add new attribute name EXTRA_CHANGED_COMPONENT_NAME in broadcast intent Intent.ACTION_PACKAGE_CHANGED for additional information for apps like Launcher. Rename a couple of parameters, the names were too jarring.
