* commit 'cc14a8393b92cd1ed6cba74829396045605ab211':
Support a single format change at the beginning of audio playback. This way the AAC+ decoder may change its output format from what is originally encoded in the audio stream and we'll still play it back correctly.
Added methods for audio effects management by audio policy manager.
- control of total CPU load and memory used by effect engines
- selection of output stream for global effects
- added audio session id in parameter list for startOutput() and stopOutput().
this is not used in default audio policy manager implementation.
Modifications of audio effect framework in AudioFlinger to allow moving and reconfiguring
effect engines from one output mixer thread to another when audio tracks in the same session
are moved or when requested by audio policy manager.
Also fixed mutex deadlock problem with effect chains locks.

Fix MPEG4Extractor to extract sampling frequency correctly when SBR is enabled.
Fixed the following problems in audio effect volume control in AudioFlinger:
- Make sure that the volumes returned by EffectChain::setVolume_l() are correct even is
no change is detected since last call
- Do not use isEnabled() to validate volume control but mState >= ACTIVE instead as the volume control
must be also active in STOPPING and STOPPED states.

First submission of audio effect library from NXP software.
This CL contains the first open sourceable version of the audio effect library from NXP software.
The effects implemented are:
- Bass boost
- Virtualizer (stereo widening)
- Equalizer
- Spectrum analyzer
Source file for the effect engines are located under libeffects/lvm/lib
The wrapper implementing the interface with the audio effect framework in under libeffects/lvm/wrapper
The code of other effect libraries has also been reorganized fo clarity:
- the effect factory is now under libeffects/factory
- the test equalizer and reverb effects are under libeffect/testlibs
- the visualizer is under libeffects/virtualizer

Modifications in audio effect engine state management.
- Separate the updating of effect engine state from the process call in EffectModule so that the state
of all effects in the same effect chain is updated simultaneusly before all process functions are called.
- Added a mechanism for the effect engine to continue being called for processing after receiving the disable
commands untils it considers that the framework can stop calling the process function without causing
a glitch or loosing some effect tail.
- Updated test reverb and equalizer to support this new feature
Change-Id: Icb56ae2c84c076d4dbad6cf733b1a62f823febe7
- Since the software encoder assumes the input is YUV420 planar,
color conversion needs to be added when the input color format
does not meet the requirement. With this patch, I only added
a single color conversion from YUV420 semi planar to YUV420
planar. We can add more as we go.

Added JAVA classes to control bass boost, equalizer, reverberation and virtualizer Effects.
Defined the following JAVA classes on top of AudioEffect class to facilitate control
off built-in audio effects with APIs aligned with interfaces defined in OpenSL ES
specification:
- BastBoot.java
- Equalizer.java
- PresetReverb.java
- EnvironmentalReverb.java
- Virtualizer.java
Split reverb API header file in two, one for preset reverb and one for environmental reverb.
Some changes in test reverb to support preset reverb.

Only send the playback complete notification if a) an error occurred on any track or b) all tracks have finished playing. The previous behaviour was to send the notification as soon as the first track finished playing.
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
