Listen to libvlc_MediaMetaChanged, and get the meta from this event/

We have to keep in mind that some meta may not interest the one who  
call load. For instance art work fetching can be really intensive.  
Currently, what you do is:
- listen to metaChanged event
- ask get_meta(Album) get_meta(Artist), etc.
Some may not be empty, some others may
- meta callback is called, and the guest program has to handle the meta.

Note, currently core treat files and remote media very differently  
regarding preparsing. Remote media may need a play, before getting the  
meta. That would need a fix in core vlc if I recall well.
