Changes to low-level audio API.

QAudioFormat::isNull() -> QAudioFormat::isValid() (inverse logic)
QAudio::SuspendState -> QAudio::SuspendedState
QAudio::StopState -> QAudio::StoppedState
QAudioDeviceInfo::deviceList() -> QAudioDeviceInfo::availableDevices()
clock() -> elapsedUSecs()
totalTime() -> processedUSecs()
QIODevice* start(QIODevice*) -> void start(QIODevice*), QIODevice*
start()

     If an error occurs, you can fetch the \l{QAudio::Error}{error
