Insufficient ProcessRecord cleanup when persistent process is killed

When persistent process with Service restarts, ActivityManagerService
does not reset ProcessRecord#hasClientActivites to false
(because ProcessRecord of persistent process is continued using
after killing).

It disturbs updating LRU list in ActivityManagerService, and then,
when new process calls ActivityManagerProxy#publishContentProviders,
SecurityException happens because of no entry in the list.

Prevent a duplicated registration of Observers

If same Observer and same URI are registered, the callback functions are called multiple times
when data identified by a given content URI changes.
It makes system slow and it cause ANR sometimes.
And When run unregisterContentObserver(), just one deleted
but others are remained in mObservers.
So add prevent code to avoid to duplicated registraion of Observers

Parallel shutdown

Decrease shutdown time by doing some shutdown tasks in parallel.

There are two threads executing during the shut down: the ShutdownThread
and a separate thread for the radio shutdown. However, the execution is
done in serial, as the ShutdownThread immediately joins on the radio
thread.

This commit will move the shutdown of the radio to the beginning of
shutdown and execute it in parallel to the shutdown of the rest of the
system.

The flow of the two threads during shutdown is now:

Radio Thread
  * Start shutdown of the radio
  * Wait for radio off or time out
  * Notify that the radio is done
ShutdownThread
  * Broadcast ACTION_SHUTDOWN as a parallel broadcast. (The receivers
    will get as much time to handle onReceive as it takes execute the
    rest of the tasks in the shut down flow. If they are not done in
    that time, we don't care.)
  * Shutdown ActivityManager
  * Shutdown MountService
  * Wait for MountService and radio to notify done
  * Vibrate
  * Low level shutdown

PS
- fix derp
