libaudioprocessing: clamp application provided float audio
For security reason, float buffers provided by application must be
clamped to FLOAT_NOMINAL_RANGE_HEADROOM.
With the new all float pipeline, float are no longer clamped by their
conversion to fixed point.
This patch adds a float buffer provider that clamps float samples
as they are copied to audio pipeline.
Test: Play music, play video in chrome (opensles format float),
play float pcm audio file specially crafter with >> 1 samples.

Audio V4: Split HAL wrapper for versioning
Both core and effect Hal now have one single point of entry.
This point of entry is their respective factories:
- DevicesFactoryHalInterface::create
- EffectsFactoryHalInterface::create
Each entry point looks for their respective services supported
version, starting from the highest (currently only 2.0) and
returning the subclass wrapping this version to the most recent audio.h
framework api.
Note that EffectBufferHalInterface were previously created from static
methods (mirror and allocate) which broke the single point of entry
requirement.
As a result, buffers have now to be created from the factory like the
other classes.
Note that the death handler also need to be its own library as it is
used by versioned code and is version independent.

Test: compile

Correctly operate on input and output buffers in DownmixerBufferProvider
Note that playback is a bit choppy, need to investigate further.

Fix crash in DownmixerBufferProvider
In ag/1768960, I forgot to actually set the buffers for the effect
interface. Without that, a 'process' method was attempting to use null
buffers.
