Fix valgrind issues
We were reading some uninitialized memory when creating bass boost and EQ

Fix THD with max user EQ preset volume again
There was a problem with previous fix in 1b6c677c where
the THD was good for max volume but bad for intermediate
high volume values.
This fix does not limit the band gains but apply a correction
to the effect bundle volume to take into account not only the
maximum band gain but also the average band gains weighted
by the proximity of each band to the max gain band.

Limit maximum equalizer gain.
Limit maximum gain in all EQ bands according to current volume so that
total gain (current volume + band gain) does not exceed a certain limit.
The gain difference between bands is preserved.

audio effects: rename configure command
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.

Fix problem in lvm effect bundle wrapper.
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.
Related to issue 5433942.

Fix device management in lvm effect bundle wrapper.
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).

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.

Fix issue 3499926.
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.

Fix several audio effects problems.
Fixed the following issues in LVM effect bundle wrapper:
- 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

Fix volume problems with insert revert
- Use a constant input level to the reverb engine and implement volume control in the
insert reverb. This avoids the volume spikes when an effect that was inserted after
the reverb is disabled or removed.
- Fix clicks (one silent buffer) at the end of the reverb disable period.
- Modified volume management in audioflinger so that the volume ramp is also done by
the insert effect if present when the track is paused (avoids clicks).
- Increased room level for all presets.
Also fixed problems with output stage session (-1):
- effect bundle wrapper was not designed to support session -1
- the permission check in audioflinger for using session -1 failed due to a wrong usage of
getCallingPid()

make sure the effect states where effect is processed are the same

volume ramp if an effect having volume control was just removed from the
effect chain.
Also fixed a crash when PCM dump is enabled in effect bundle wrapper.

- 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.

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
