Mikhail Naganov 4f339476d3 audio: Implement the major functionality of the primary CF HAL ...

Core HAL changes:

1. Add StreamPrimary implemented via StreamAlsa.

2. Align the configuration with the HIDL HAL.

3. Fix position retrieval vs. standby call.

4. Fix sleeps in StreamAlsa.

VTS changes:

1. Use several bursts for stream I/O test scenarios that check
   observable position increase. This is because the position may
   not be available until a couple of transfers have been made.

2. Do not require position increase for the scenarios that do
   not make several bursts. As specified above, the position may
   not have been increased for the ALSA case. Whereas, using
   multiple bursts in all scenarios will increase test time, and
   make the state machine transitions graph more complicated.

3. Hook up the test config file to shut down audioserver during
   VTS tests, fix the test config file.
