Subject: commands, dvd, dvdnav, bluray: cleanup sub/audio track language
 display

Code cleanup: Use a stream_control instead of global functions to
get the language associate with a audio or subtitle stream from
the streaming layer.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@34736 b3059339-0415-0410-9bf9-f77b7e298cf2

Support showing the stream language with br:// playback.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@34737 b3059339-0415-0410-9bf9-f77b7e298cf2

Fix DVDs showing the subtitle language as "unknown"
for a long time.
