take account of RotationVector's new extra parameter

Rotation vector has a new 5th parameter introduced in API 18. But the code classified the 5 parameter the same as it would be 3 and overriden the 4th parameter which is unnecessary and also caused an unexpected behavior.

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

Change SQL to improve performance.

To know the number of images, use "COUNT(*)" instead of "_id" in SQL.
Using "_id" gets all result set. and when getCount() is called, CursorWindow is filled.
But using "COUNT(*)" gets just 1by1 data.
So using "COUNT(*)" is more faster than now.
And this SQL is called everytime per a file during a file transfer in MTP
The better way is by using "EXIST".
But if using "EXIST", modify MediaProvider.call() method.
So i applied just a "COUNT(*)"

Fix progress of VolumePanel never refresh

On some occasions when disconnecting a headset it is possible for
the volume slider to enter a state where it is no longer updates.

The cause was that ProgressBar enters a state where a call to
doRefreshProgress no longer updates the progress.

The solution was to make sure mRefreshIsPosted is set to false
when mRefreshProgressRunnable is removed.

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.
