Buffers are not allocated and thread is not created until the first call where voice is required. Adds a different callback (sync_callback) to buflib so that other sorts of synchonization are possible, such as briefly locking-out the PCM callback for a buffer move. It's sort of a messy addition but it is needed so voice decoding won't have to be stopped when its buffer is moved. Change-Id: I4d4d8c35eed5dd15fb7ee7df9323af3d036e92b3
