      - New playlist_info structures and accessors
        It works pretty like the old input_info (with categories)
        It provides modularity to the playlist
      - Removed ppsz_options and i_options from playlist_item
        (we use the special category Options)
      - Added a unique id to each playlist_item to be able to track the
        items accross playlist reorders
      - Simplified adding of items.
           - playlist_AddExt is removed
           - playlist_AddItem is still here and exported but should not be used
           - use playlist_Add( p_playlist, uri, name, duration, mode, pos )
             and use the accessors for all other things
      - Added setters for fields of the playlist_item structure
      - Introduced "item-change" and "playlist-current" playlist variables
        to give more flexibility than only intf-change

      At the moment, duration is still in the structure (easier to use, IMHO)
