#7639: DVD: audio streams get the 'Unknown language' in audio track map

Hi,
I noticed that with the DVDs I checked the codec did not set the audio
language code in 'AvFormatDecoder::ScanStreams' resulting in the audio
streams being saved in 'Unknown Language' internally.
This does not seem to be a bigger issue as the OSD gets its information
about the tracks directly via dvdnav and not via the track map.
I added some code to get the language info for the track map via dvdnav as
well in case of DVDs and created a patch for this.
When testing the patch I ran into a bug that was shadowed by all audio
tracks always having the unknown language: the stream selection in
'AvFormatDecoder::AutoSelectAudioTrack' exited early in case the audio map
contained more than 1 language. I fixed this as well as part of the patch
as it will only create more problems otherwise.
The patch is against release-0-22-fixes.
Please let me know if you need more information or testing.
Best wishes,
Martin.
