a2c714129e audio: Add StreamDescriptor.frameSizeBytes 
This field indicates the frame size and is filled by
the HAL module, so that the client does not have
to calculate it.

As a side effect, in the VTS code, a StreamContext can
now be created solely from a StreamDescriptor.

Added unit tests for the functions from Utils.

6a4872dff0 audio: Implementation of audio I/O, part I 
This patch adds necessary structures and prepares for implementing
data flow for audio I/O.

Also in this patch we clarify the relationship between audio patches
and buffer size for audio I/O, and between buffer size and latency.
