Floating point support for audio post processing components
Source code is added/modified to support floating point processing for
audio post processing components.All the changes are done under the macro
BUILD_FLOAT
Enable/disable this macro in Android.mk files to build floating point or
fixed point code.
Based on the macro either fixed point code or floating point code gets compiled.
By default this macro is ENABLED.
(cherry picked from partner commit 2ceaff6aafadbcb0fb6d5135ca814ba7c790ab1a)
(Minor merge conflicts solved, some formatting and safety changes,
bugfixes in EffectReverb.cpp)
Test: audio comparisons between integer and floating point effects

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
