Fix dest == src bugs in Matrix.cpp.

The main bug was that the AutoJavaFloatArray autoSrc was not passing in
read only. This meant that the destructor overwrote the data which
the autoDst AutoJavaFloatArray had written in it's destructor.
This case only happened if src == dest and the arrays were copies.
Also improved performance by passing in read only a few other places.

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.

NsdService does not clean up after exiting clients

When a client of the NsdService exits, NsdService should
clean up the requests it has sent to the mDNS daemon:
cancel any pending resource-discovery and resource-resolution
queries, and remove any services registered by this client.

If this isn't done, several bad things happen. The daemon will
continue to run unnecessarily, will report service discoveries
that can't be forwarded on to the client, and will continue to
advertise service ports for an application which is no longer
running until the device is rebooted (mDNS pollution).

NULL previous background bitmap upon changing wallpaper

Step to reproduce it on Nexus 10 with 4.4.2(KOT49H):
1. Long press on home screen.
2. Choose wallpaper from Wallpapers.
3. Select new wallpaper and set it.
4. Repeat step 1-3 several times.
See black background instead of the wallpaper.

There are two binder objects who hold reference to the
ImageWallpaper$DrawableEngine, which keeps the big chunk
bitmap from being recycled.
One is WallpaperService$IWallpaperEngineWrapper. The client
references went away slowly, maybe several minutes after
changing wallpaper. Then the finalizer has to been executed
to GC it.
The other one is WallpaperService$Engine$BaseIWindow. Don't
know who still held reference to it even after the window
was removed.
Anyway, let the bitmap be GCed first.

remove unnecessary switchUser call

If userId doesn't change, no need to do switchuser.or it will
introduce some tweak for gps modules in quick off/on because
they need cost time in off/on.

Fix to memory leak leaving WallpaperCropActivity.

After running wallpaper cropper serveral times it crashes with
an OutOfMemotyException.

When leaving WallpaperCropActivity all textures are leaking until end
of process lifetime. This is due to a missing call to function
TiledImageView.destroy which in turn assures TiledImageRenderer
releases held resources.

Resolved by assuring WallpaperCropActivity calls TiledImageView.destroy
from WallpaperCropActivity.onDestroy. In case where onDestroy is not
called resources will be released anyway by process being brought down.

Null pointer exception in FileRotator.java

Sometimes a null pointer exception is thrown when examining files
managed by the file rotator.

The logs from the test show that the Wifi state is changed a large
number of times. On every state change, a write operation is
initiated on the file system. This will eventually result in out
of memory and the call to mBasePath.list() in the maybeRotate(...)
method in FileRotator.java will return null so the iteration will
throw a NullPointerException.

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.

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

Lockscreen Blur: Disable if music is playing

Some apps don't employ full screen album art.
In that case album art doesn't override wallpaper & content behind screen is clearly visible.
This fixes that issue.
