Removed dead/buggy code in AudioEffect.getParameter() and
AudioEffect.command() that was meant to return the actual length of
meaningful data in the returned parameter or command reply.
This is replaced by the method return status indicating this length when
positive (negative return codes still indicate the same errors as before).
Modified automated AudioEffect tests accordingly.

android_media_Visualizer.cpp:
Delete local reference to jArray in captureCallback() in
the case of waveform capture.

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

- Created sub-package android.media.audiofx for audio effects.
- Hid AudioEffect class contructor, methods and variables not needed by
applications
- Added more javadoc comments for AudioEffect Class

The type of the cmd, cmdSize and *pReplySize parameters of the effect control interface command()
function have been modified from int to uint32_t. This is more consistent with their role.

a single call.
Addional changes:
- Fixed simulator build
- Use effect interface UUIDs from OpenSL ES includes when available
- Added cleanspec rules to remove now obsolete test effect libraries
- Fixed bug in AudioEffect JNI setParameter function.

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

Effect API:
- Use different definitions for audio device, channels, formats... in AudioSystem and EffectApi:
Removed media/AudioCommon.h file created for initial version of EffectApi
- Indicate audio session and output ID to effect library when calling EffectCreate(). Session ID can be useful to optimize
the implementation of effect chains in the same audio session. Output ID can be used for effects implemented in audio hardware.
- Renamed EffectQueryNext() function to EffectQueryEffect() and changed operating mode:
now an index is passed for the queried effect instead of implicitly querying the next one.
- Added CPU load and memory usage indication in effects descriptor
- Added flags and commands to indicate changes in audio mode (ring tone, in call...) to effect engine
- Added flag to indicate hardware accelerated effect implementation.
- Renamed EffectFactoryApi.h to EffectsFactoryApi.h for consistency with EffectsFactory.c/h
Effect libraries:
- Reflected changes in Effect API
- Several fixes in reverb implementation
- Added build option TEST_EFFECT_LIBRARIES in makefile to prepare integration of actual effect library.
- Replaced pointer by integer identifier for library handle returned by effects factory
Audio effect framework:
- Added support for audio session -1 in preparation of output stage effects configuration.
- Reflected changes in Effect API
- Removed volume ramp up/down when effect is inserted/removed: this has to be taken care of by effect engines.
- Added some overflow verification on indexes used for deferred parameter updates via shared memory
- Added hardcoded CPU and memory limit check when creating a new effect instance
Change-Id: I43fee5182ee201384ea3479af6d0acb95092901d
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.
