CRAS: dev_stream - Scale captured samples when mixing to dev_stream if needed
Scale captured samples in dev_stream_capture when the samples are
copied from input buffer. Pass the software gain scaler to
cras_audio_area_copy and do scaling optionally in
cras_mix_add_scale_stride.
There are two reasons to scale when adding the samples.
1. Stream might read only part of the input buffer. If we scale in input buffer,
we may scale same sample multiple times.
2. There might be multiple input devices. If we scale in audio area of
dev stream after mixing samples from a device, we may scale same sample
multiple times.
Let audio_thread pass 1.0f scaler for now. In the future patch it will pass a
gain scaler when needed.

More info than just the format bytes will be needed to support formats
other than s16_le in audio_area_copy.

CRAS: dev_stream - track read offset per device.
Similar to how output devices work, track each stream's read offset
into the device. This will allow streams that need SRC to read less
than the maximum amount of frames.
BUG=chromium:421941
TEST=play and record from multiple devices.

CRAS: audio_area - Rename src_index.
Switch src_index to skip_zero. The new name is a better indication of
what this parameter is used for.
