AudioService: Fix absolute volume for AVRCP

Avrcp.java uses max volume obtained by getStreamMaxVolume() when
converting to AVRCP levels and it returns non-scaled volume index.
For this reason volume index needs to be dispatched to Avrcp before
scaling as otherwise Avrcp will convert volume level incorrectly,
i.e. max volume index for music stream is 15 and any volume index
>1 (>10 after scaling) will result in setting *MAXIMUM* volume level
on headset which is not safe for listener.

Volumes in Settings/Sound is slow to start

There is a delay after pressing volume menu item
there is a delay until the Volume popup is shown.

The reason for this is that the initialization of
the different seekbars is slow and run in the main
thread. More specifically the call to get the
ringtone from the RingtoneManager is causing this
delay.

Moving the call to the ringtone manager to the
handler thread used to play ringtones to make
the launch of the volume dialog a bit snappier.

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

Fix setSurfaceTexture to handle surface caching

Changed the TextureView.setSurfaceTexture to apply the
existing listener to the surface provided in the method.
This is done to allow surface caching to work.
Whenever a new SurfaceTexture gets created, its listener is
created as well, so when the setSurfaceTexture is called
we should be attaching the listener to the new surface.

PEEK [1/2]

Sensors are fully disabled when screen is on. When you turn the screen off,
it will start polling both gyroscope and proximity sensor values. If it detects
using the gyroscope sensor that device is lying on a table, it disables proximity
polling. If it detects with proximity sensor that it is in your pocket, it disables
gyroscope polling. This way, we save some battery from the beginning. Later, when you
receive a notification, it enables a partial wakelock (CPU on but at low frequency),
and starts listening for movement, either from getting it out your pocket or lifting
off from the table. If it detects those events, it will turn on screen and show the notification.
Wakelock timeouts on 10 secs, so if you receive a notification and there is no movement in that time,
sensors will stop polling after that time, disabling peek interaction until a new notification comes.
Peek doesn't process low and min priority notifications.
