Add support for scaling mode parameter
Support VISUALIZER_PARAM__SCALING_MODE parameter.
Modify process() function to use new volume scaling parameter,
used to set whether captured values are maximized by current
headroom in the buffer (default existing behaviora) or left
as is and thus affected by volume.
Modify AudioEffect to allow subclasses to override the following
events: control status changed, enable status changed, command
executed.
In Visualizer class (a subclass of AudioEffect), reset the
scaling mode and capture size on the actual effect
as cached when control is regained.
This will allow the effect to be properly
configured whenever Visualizers with different scaling
modes or capture sizes are released (e.g. from java
release() method).

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

Moved and renamed effect API header files
Moved specific effect header files to
system/media/audio_effects/include/audio_effects
and renamed to lower case (effect_xxx.h).

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
