 This patch adds the ability to record and play radio channels transmitted
 on DVB.  They can be recorded or played live just like the television
 channels.

 It works by adapting the idea of the dummy dtv recorder to generate an
 additional video stream to go along with the audio and locks the video by
 setting the time stamps of the video packets to match the audio stream.
 That means that all the frontend code that assumes that there is a video
 stream works without any change.  The recording has the keyframes that are
 needed for seeking.  The patches are all in the backend and almost
 entirely to dvbrecorder apart from very minor changes to allow radio
 channels to be included in the scan and EIT information.

 It does increase the size of the recorded files compared to recording the
 audio alone but not by an enormous amount since the dummy television
 images are very small.
