There can be different use cases with the code that imports
headers from audio_effects (each subsequent case is a more
specialized version of the previous one):
1. The code only needs access to general structures
like effect_descriptor_t:
==> include system/audio_effect.h
Example: AudioSystem in libmedia
2. The code that needs access to effect UUID and parameter
enums:
==> include system/audio_effects/effect_foo.h
Examples: media framework effects interfaces, libwilhelm
3. The code that needs to call into HAL:
==> include hardware/audio_effect.h
Examples: libaudiohal (implementation part) and libeffects
4. The code that implements a particular effect:
==> include audio_effects/effect_foo.h
Examples: cts/.../CTSTestEffect.cpp
stuff in hardware/, vendor/

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

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

Added AudioEffect C++ class. AudioEffect is the base class for effect specific implementations,
OpenSL ES effect interfaces and audio effect JNI.
Added the AudioEffect JNI and AudioEffect JAVA class. AudioEffect is the base class
to implement more specific JAVA classes to control audio effects from JAVA applications.
