In DOWNMIX_TYPE_FOLD mode, add support for variants of quad and
5.1 channel masks where the "side" channels are used instead of
the "back" channels. These variants have the same channel order,
so they can share the same downmix function.

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).

In the AudioMixer structure associated with each track, add an object
that acts as the buffer provider when the track has more than two
channels of input in the mixer. This object, DownmixerBufferProvider,
gets audio from the actual buffer provider of the track, and applies
a downmix effect on it.
The downmix effect is created and configured when the track gets
created in AudioFlinger, which causes AudioMixer::getTrackName()
to be called with the new track's channel mask. It is released
when the track is disabled in the mixer.

Current method implemented by the visualizer to detect that audioflinger has
stopped providing audio buffers does not work if the application
reads pcm captures too fast.
The fix consist in implementing a method based on real time measurement only.
One drawback is that the new method makes use of system calls that add some
overhead to the process and capture functions.

First pass at implementing an audio effect whose role is to
downmix multichannel PCM buffers to stereo.
The effect is not handling volume changes.
The effect code here handles quad, 4.0, 5.1 and 7.1 input configurations,
to optimize the most commom configurations, and does not yet handle
generic multichanel configurations.

Do not set the effect state back to configured when a configuration
command is received while the effect is enabled. Instead just check that
the new config is the same as current config.
It is normal to receive a config command from the framework while enabled
if a new effect is added on the same session.

Several source files privately defined macros LIKELY and UNLIKELY in terms
of __builtin_expect. But <cutils/compiler.h> already has CC_LIKELY and
CC_UNLIKELY which are intended for this purpose. So rename the private
uses to use the standard names.
In addition, AudioFlinger was relying on the macro expanding to extra ( ).

Renamed audio effect library interface command for audio format
configuration from EFFECT_CMD_CONFIGURE to EFFECT_CMD_SET_CONFIG.
This makes the naming more consistent with other exixsting commands
and allow adding a new command to get the configuration (EFFECT_CMD_GET_CONFIG).
Same change for reverse channel configuration renamed from
EFFECT_CMD_CONFIGURE_REVERSE to EFFECT_CMD_SET_CONFIG_REVERSE.
Implemented EFFECT_CMD_GET_CONFIG in exisitng effect libraries.

The virtualizer and bass boost effects should be disabled when
not playing throught headsets or headphones.
There is a bug in current wrapper implementation that makes that those
effects are not disabled if the effect is enabled by the user after
the headset has been removed (current logic only works if the device selection
occurs while the effect is enabled).

When an effect is disabled, the process function should either
copy or accumulate the content of the input buffer to the output buffer
depending on the behavior requested by the framework.
Current implementation is copying the input buffer unconditionally.

Audio effect framework is extended to suport effects on
output and input audio path.
AudioFlinger: Support for audio effects and effect chains is
moved from PlaybackThread class to ThreadBase class so that
RecordThread can manage effects.
Effects of type pre processing are allowed on record thread
only. When a pre processing is enabled, the effect interface handle is
passed down to the input stream so that the audio HAL can call the
process function. The record thread loop calls the effect chain process
function that will only manage the effect state and commands and skip the
process function.
AudioRecord: The audio session is allocated before calling getInput() into
audio policy serice so that the session is known before the input theead is
created and pre processings can be created on the correct session.
AudioPolicyService: default pre processing for a given input source are
loaded from audio_effects.conf file.
When an input is created, corresponding effects are created and enabled.

Modified the effect library API to expose a library info structure

Also removed enums for audio channels, audio format and devices
from effect API and use values from system/audio.h instead.
Modified effects factory to support new library interface format and
load libraries and efffects listed in audio_effects.conf file.
The file audio_effects.conf is first loaded from /vendor/etc and
then from /system/etc/audio_effects.conf if not found.
Modified existing effect libraries to implement the new library interface.

Make sure that NumberEffectsEnabled is decremented at the same time as
SamplesToExitCountBb reaches 0 in Effect_process(). Not doing so
causes NumberEffectsEnabled not being decremented if Effect_setEnabled()
is called after SamplesToExitCountBb reaches 0 and before next Effect_process() is called.

- memory leaks in EffectCreate() in case effect creation fails at various stages
- Added saturation when accumulating to output buffer
- Fixed problems with enabled effects count when an effect is released while enabled
- Do not allocate temporary buffer for accumulation each time process() is called
Fixed the following issues in effects framework (AudioFlinger)
- Release effect synchronously in the library when deleted from effect chain
- Do not call the effect process function if no tracks are present in the same
audio session
