This will be used to replace the current filtering code with a token
comparison for each track.

I'm hitting this problem while developing 6.5, since file formats are

This patch changes versioning problems into fatal errors to prevent us

The pl_artist_init() function is used to allocate a playlist for each
artist already in the database, and pl_artist_deinit() is then used to
free up this memory during cleanup.

System playlists cannot be created or deleted, so these functions simply
return false in this case. Library playlists will use this to add new
library paths to Ocarina.

I also take the opportunity to add in a generic lookup function to
convert a library path into a playlist.

This function is for both adding and removing tracks, and only returns

Similar to the library tag, this is a void pointer that should only be
used by the playlist layer.

I decided to set this as a void pointer to keep other layers from using
the playlist without our knowledge. The only user of this variable
should be the playlist code.

I was storing database indexes, but this assumes that database indexes

I don't think it makes sense that callers of file_open() are expected to

The track database now tallys total play count and unplayed track count,
