There is a problem in AudioEffect and Visualizer native_setup() methods
that causes a crash in the application after the mediaserver process
has crashed and restarted.
The problem is that the native AudioEffect/Visualizer constructor is
called while the JNI is in critical state after calling
GetPrimitiveArrayCritical(). As the mediaserver process just restarted, the
first call to AudioSystem will cause the binder IAudioflinger interface to
be reteived and a callback send to AudioSystem JNI to clear the mediaserver
error state. This will call env->FindClass() and crash due to the JNI being
in critical state.
Also fixed a similar problem in AudioTrack JNI

The visualizer enables application to retrieve part of the currently playing audio for visualization purpose.
It is not an audio recording interface and only returns partial and low quality audio content as a waveform or
a frequency representation (FFT).
Removed temporary hack made in MediaPlayer for animated wall papers based on audio visualization (snoop() method.
This commit also includes a change in AudioEffect class:
- the enable()/disable() methods have been replaced bya more standard setEnabled() method.
- some fixes in javadoc
