This avoids confusion with parent class AudioEffect's mLock which is
protected.

58d3bd0810 Visualizer: replace the FFT implementation with a faster one.
This implementation uses fixed points instead of floating points. It
is slightly inaccurate compared to the old one but still perfect for
visualization purpose. It runs 40% faster on passion, 5 times faster
on sholes, and of course 14 times faster on sapphire.

df9b81ced4 Added Visualizer effect.
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
