The readd(), readu(), and readhu() functions are all used to read
various forms of integers. The readl() and readw() are for reading
either lines or individual whitespace-delimited words

I'm going to create a unified struct file that should be able to share
code between data and cache files. The first step is to push the old
structure to the side so it can still be used in other places.

There might be rare occasions where users want to play a track that
exists outside their music library. This patch adds support for
allocating and freeing these external tracks without adding them to the
track database.

I'm struggling to come up with a good way to combine code for this with
code for track_add(), since the lookup mechanism is basically the same.
I'll keep them separate for now and think on it some more.

This is useful for user playlists so they can store their playlist-id
directly, letting us remove the entire playlist_get_id() function.

This lets up update track keys to prevent duplicates showing up during a
library path update.
Fixes#93: Library sometimes has duplicated tracks

This was added so tracks could bump the libary tag size. Now that the
size field has been removed, we can remove this function.

This makes file versioning way easier, since every file will have the
same version. I'll still need to manage minimum-supported versions, but
that shouldn't be too difficult going forward.

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.

The track tag doesn't need these tags now that they can be found in the
album tag.
Implements #64: Remove Artist and Genre pointers from Tracks
Signed-off-by: Anna Schumaker <Anna@NoWheyCreamery.com>
Artist and genre information are already saved by the album tag. In
addition, we can save a single date stamp instead of (year, day, month)
triplets.

I plan to change the file format of some tags, so add versioning so we
can change things at different times.

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.

Albums tend to have a single genre for all tracks, so it makes more
sense for an album to point to genre information.

I was storing database indexes, but this assumes that database indexes
are constant. I intend to change this with database defragmentation.
Implements #46: Filter stores a track pointer

This is used to remove tracks from the filtering index. We'll need this
once we switch over to storing pointers to keep the same track from
getting added multiple times.
