This lets me "pause" playing queued tracks in favor of other playlists.
I remember the previous playlist so we can resume track picking once the
queued tracks playlist is empty.

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 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.

And perform an upgrade when reading back in. After track tags are read,
we can save the database in the new format and remove the old tags.

This allows for representing albums with multiple genres. I know this
doesn't happen too often, but it doesn't hurt to be covered. At the
very least, now we have a genre id for constructing new albums!

I need a way to represent the same album with different artists to
account for multi-artist albums.
Signed-off-by: Anna Schumaker <Anna@NoWheyCreamery.com>
The date stamp is a single value that represents year, month, and day.
This should be slightly easier than working with three separate values.

Removing items from the database leaves a NULL pointer "hole" that is
never filled in. This doesn't affect correctness, but it could be
wasteful as items are added and removed. This patch adds a function to
defragment the database without changing the order of items.
Implements #66: Add support for rebalancing databases

I plan to change the file format of some tags, so add versioning so we

This is needed to handle track database defragmentation, but could also
be expanded on later to save playlists from a generic place.

The settings code is designed to map strings to unsigned integers, which
is exactly what we do here. This lets us cut out an extra file access,
which is always a plus. We remove the audio file after upgrading to
prevent reading it multiple times.

I initially tried making several helper functions to reuse code and make
it easier to add new playlists. This didn't work all that well, mostly
because glib wasn't able to expand variable values or find the line
number that errors occured on. Macros don't have this problem, since
they are expanded at compile time.

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.

This isn't as important for established playlists, but this string could
quickly become an invalid pointer for new playlists that are added.
Signed-off-by: Anna Schumaker <Anna@NoWheyCreamery.com>
Library playlists call this when deleting tracks, otherwise we could end
up dereferencing invalid pointers the next time we use the artist
playlist.
