Add property to ignore audio effects on the platform
Use boolean property ro.audio.ignore_effects to load or ignore the
audio effects.

fix deadlock issues that arise when there are simultaneous
effect control interface calls to proxy and to
non sub-effect wrappers(eg., bundlewrapper) from audioflinger
Also, return NO_ERROR when CMD_OFFLOAD succeeds
Whenever there are parallel calls to proxy and non sub-effects wrappers,
some of the calls are not completed. This is due to deadlock arsing out
of Proxy waiting for the subeffect call to return and subeffect waiting
for proxy to release lock.
The call flow is changed to a cleaner and simple one - Proxy gets the
aeli(effect library info) of subeffects during the EffectGetSubEffects()
call. Therby, proxy will manage the sub effects by itself rather than
going through effects factory.

Effects Factory changes for effects offload
audio_effects.conf - commented changes to illustrate the
addition of Proxy and sub effects to the conf file
Added an effectFactoryApi - EffectGetSubEffects for querying the
sub effect descriptors from the factory. This api is used by the Proxy
to get the sub effects
Added functions and data structures in factory code for
loading the sub effects
gSubEffectList - has the Proxies and their corresponding sub effects
- addSubEffect() - reads a sub effect node and adds to the gSubEffectList
- findSubEffect() - searches through the gSubEffectList to find a SubEffect
Bug: 8174034.

Audio framework: support for audio pre processing
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.

New effect library API
Moved and renamed media/EffectApi.h to hardware/audio_effect.h
Modified the effect library API to expose a library info structure
containing an interface functions table.
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.

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
