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. Bug: 286914845 Test: atest VtsHalAudioCoreTargetTest Test: compare APM dumps for AIDL vs. HIDL Change-Id: I85271564c664fa40008d60e82b32eaa66a99c68f
