Audio HAL: fixes for issues discovered after client conversion
Several issues addressed:
-- added IDevice.supportsAudioPatches to query whether
create/removeAudioPatch is actually supported by HAL;
-- IStreamOutCallback proxy needs to be owned by IStreamOut
implementation. In order for the client to reset the reference,
added method IStreamOut.clearCallback;
-- IDevice.open{Input|Output}Stream need to return a "suggested" audio
config from HAL;
-- code for converting between system/audio.h and HIDL
data structures has been moved to
android.hardware.audio.common@2.0-util library for reuse;
-- added a workaround for the issue with QC effects HAL trying to write
into the input parameters buffer, which is r/o by Binder design.
