    Fix crash in RTP Player on stop and close
    
    When dragging the UI, this somehow causes a great lag. Then by
    spam-clicking on the Stop button, a double free seems to occur.
    
    Fix this by moving the audio cleanup to the outputStateChanged callback
    as documented at https://doc.qt.io/qt-5/qaudiooutput.html. Note that
    calling stop() in the IdleState also triggers a change event, resulting
    in the desired cleanup.
    
    Stop streams before the dialog is closed (via accept/reject). This
    *cannot* be done in the destrutor of RtpPlayerDialog because destructing
    QAudioOutput processes events from the event queue, resulting in
    preature destruction of other objects... crash.
