WebAudioSourceProvider should be thread safe ref counted since it can be refer from main thread and audio thread.
Created attachment 313449 [details] Patch
This change is needed since we are now calling prepare from the audio thread but we apparently want to call m_client->setFormat from the main thread. Maybe we could make setFormat be ok when called from the audio thread if we would like to stick with RefCounted<>. It seems safer to go with ThreadSafeRefCounted for now.
