73b06adb9a audio: Allow Module subclasses to customize stream creation
Since specializations of the 'Module' class likely need
to provide their own specializations for streams, provide
virtual methods for them.

efe980bb44 audio: Refactor streams implementation
Simplify the experience of implementing stream variants.
Stream class now exposes two interfaces: DriverInterface
and StreamCommonInterface, which represent the two
aspects of its usage: via the FMQ on the worker thread,
and via IStreamCommon Binder interface.

Input/output streams now inherit the concrete stream
variant, and implement interface methods specific for
IStreamIn and IStreamOut.

Added DriverInterface::shutdown method which is called
on the worker thread prior to the exit.

e48e5737f3 audio: Make I/O operations in default stub more realistic
1. Increase the minimum buffer size to 256 frames. This is
   more realistic than 16 frames: 256 frames is ~5ms @ 48 kHz.

2. Make transfer delay in the stub module dependent on the frame
   count for synchronous transfers.

f429c03d49 audio: Generalize stream implementations
This allows for more code reuse and composability when
implementing streams for a particular audio "backend."

The existing "stub" code has been moved to StreamStub* files.
