Add 'MicrophoneInfo' and 'MicrophoneDynamicInfo' parcelables.
Add IModule.getMicrophones method.
Add following methods to IStreamIn:
- getActiveMicrophonesIds;
- get/setMicrophoneDirection;
- get/setMicrophoneFieldDimension.
Provide trivial implementations and VTS.
Also slightly refactor port retrieval from ModuleConfig
to unify common queries.

Introduce IStreamCallback interface for non-blocking I/O. Add 2
new stream states: TRANSFERRING and TRANSFER_PAUSED, and define
state machines for the async case. Add DrainMode as in previous
HAL versions.
Note that non-blocking input is not fully implemented because it
did not exist in previous HAL versions, and the corresponding
AudioInputFlag does not exist yet.
Enhance VTS state machine tests to allow waiting for an async
event.

Instead of using 'STATUS_NO_INIT' in the case when stream
position can not be reported, use a special value for Position
fields. This streamlines processing of statuses on the client
side, by removing the need to treat 'STATUS_NO_INIT' specially.

Add ModuleDebug.streamTransientStateDelayMs parameter to ensure
that streams stay in transient states for the specified amount of
time. This enabled sending commands from VTS while the stream is
still in a transient state.
Add 'getStatus' stream command to retrieve current positions,
counters, and stream state. Previously we were planning to use a
zero-sized burst command for that, however, after the
introduction of stream state machines, the 'burst' command is
not handled in every stream state, and may even affect the
current state, thus it's no more usable for this purpose.

Previously StreamDescriptor::Command used to be a parcelable
holding a command code (enum) + a command argument which was
used for one command only. This got replaced with an equivalent
union, where each command w/o arguments is represented by a
'Void' variant, and the command with an argument with a variant
of a corresponding type.
This has the following benefits:
- the union guarantees that the argument is only set for
commands that actually use it, thus all related comments
and validations can be removed;
- the command dispatch can be turned into an exhaustive
switch.
To be able to use an exhaustive switch, the 'exit' command
has been exposed at the interface, but marked as 'hal_reserved'.

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.

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.

(cherry picked from commit 5862c1e3bc)
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.

(cherry picked from commit 01803d454a)
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.
