[git version control]

vlc | branch: master | Rémi Duraffort <ivoire at videolan.org> | Tue Feb  2 10:22:00 2010 +0100| [ae749fcdc0e2a5a1a174daebd60632ccc12ae639] | committer: Rémi Duraffort 

libvlcpp: add a function to get the audio infromations from the media player.

The Audio class can only be created/destroyed by the associated MediaPlayer
class. I will add some copy constructor later on.
