cce8e5f39d audio: Add pause, resume, and standby stream operations
Clarify and verify in VTS that the data FMQ of StreamDescriptor
is a transient buffer. The consumer must always read its entire
contents. This is the same behavior as in the HIDL HAL.

Define the state machine for streams and the set of commands for
transferring between states.

Clarify and verify in VTS that the frame counter of the
observable position must never be reset.

Implement commands for the synchronous I/O case.

Refactor stream test logic to simplify testing of state
transitions.

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.

4f5d3f12f5 audio: Implementation of audio I/O, part II
This patch implements audio I/O for the synchronous, non-MMAP
case.

Updated the StreamDescriptor structure to make it usable.
Clarified comments on the expectations for the client and
the HAL module.

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.
