io-audio based audio management for QNX 7.0.0
Add code to setup and handle io-audio based audio management
notifications.
Add InterruptedState to QAudio::State. Indicates that this
stream is in a suspended state because another higher priority
stream currently has control of the audio device. Playback
cannot resume until the higher priority stream relinquishes
control of the audio device.
Adjust the documentation for QAudio::State SuspendedState to
reflect the fact that audio management events can also put the
stream into this state.
Add InterruptedState handling to the spectrum example.
