Message:

Audio: Added geberuc asynchronous init to DrvAudio for use in WAS (and maybe others). bugref:9890

• Added optional asynchronous init via a worker thread pool in DrvAudio (pfnStreamInitAsync).
• Added interface for the backend to use the thread pool from the backend (pfnDoOnWorkerThread).
• s/PDMIAUDIONOTIFYFROMHOST/PDMIHOSTAUDIOPORT/g
• New BACKEND_READY state flag (a bit confusing wrt to INITIALIZED, but whatever).
• Don't RESUME streams which aren't actually paused (on VM resume).
• Restore the backend state correctly when the per-direction enable flag is changed in DrvAudio. Would enable the streams regardless of actual state.
• Move more PDMAUDIOSTREAM members from the public structure and into the DRVAUDIOSTREAM.
• ++
