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.

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 Change-Id: Id092a1340e9e38dae68646ade7be054e3a36980e
