This adds a new driver for audio in libretro builds for devices with multithreading support that defers audio rendering to a worker thread provided by the libretro frontend. The threaded driver has the advantage that video lag will not also cause the audio to lag, which is very noticeable since it manifests in the form of audio crackling when it happens.
