It's possible that the user may pass us a subdirectory of a path that
has already been added to the library. We can use this to prevent
double-adding tracks if the user does this. Additionally, this function
can be used to help look up tracks using only a filepath.

Databases can change either as part of an upgrade or through adding and
removing entries. We can save a bit of memory by removing unallocated
entries during startup.

This was used to display the number of tracks in each library path. We
can use playlist functions to get this information now.

This was used to enable and disable library paths in previous Ocarina
versions. This isn't used anymore now that we have library-based
playlists.

The dbe_index of a given database item might change in the future, so we
can't rely on it everywhere. Let's just use it for saving and loading
files, with the expectation that changes will happen sometime after
startup.

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.

It doesn't make sense to have a subdirectory with a single file. Let's
move it back to core/

We now have an interface for controlling everything through struct
db_entry, so let's just have the database store a db_entry directly.

For allocating new database items from a given key. Tracks do not need
this function since we have special handling for creation and insertion.

It's easier to just pass off the library database rather than forcing
higher layers to iterate over the entire thing (including possible
invalid entries).

I also have to replace the "library" namespace with the "collection"
namespace to avoid naming collisions.

This patch moves the library_db into tags/library.cpp, where it can be
effectively managed by the Library tag. For this to work, I need to add
some extra functions to the tags namespace to:
- Create new Library tags,
- Find tags by index,
- Remove the Library at a specific index, and
- Find the actual size of the library_db.
