This should offer a performance increase since the item to insert will
only be copied if it is not already in the database.

Inserting into a vector can sometimes cause the entire vector to
reallocate itself. The insert() function returns a pointer to the
caller, so this reallocation could invalidate the returned pointer.
This is not what we want.
Instead, store pointers to the data in the vector. C++ provides a
default copy constructor that can be used to allocate a new item before
inserting. By doing it this way callers won't have to allocate memory
themselves. In addition, I will no longer need to keep a valid bit
since we can simply check for a NULL entry in the database.

This gives me the item directly, which is usually what I want when I
call these functions. Save iterators for iterating.

Rather than returning an index into the database, instead return an
iterator pointing at the item we just inserted.
Signed-off-by: Anna Schumaker <anna@ocarinaproject.net>
Calculating through the iterator may lead to unexpected problems. We
already know the id of every database entry, so we might as well use it
directly.

If a title began with a number then the number would be read as part of
the length, adding extra time. So a track with length "100" and title
"42 abcde" would be read back as having length "10042" and title "abcde"

- Double check that track->valid == true before notifying the UI that
there is a new track.
- Use primary_key() instead of manually calculating the full filepath.

Recalculating this doesn't change the runtime significantly, so we might
as well save some disk space.

I updated the design and rewrote the unit tests. This creates something
more consistent with how I ended up using the index.

I add:
- Autosaving option
- Real iterators
- Better accessor functions
The new design and unit test also allows me to remove the 300,000+ line
"database.good" file that the old tests were based on.

I changed primary_key() into a function since it is only called once,
and there is no point in using more mmemory than I need to. I also
created a basic unit test for everything that database entries are
supposed to do.

When a track finishes, I tell the library to update playcount. Then,
the library triggers a callback to the playqueue deck telling it to
update.
This patch also finds and prints the track that causes a gstreamer
error.

I don't have user-configurable sorting (yet), but for now I'm sorting by
Artist -> Year -> Track #.
I also fix a bug where the library wasn't lowercasing artist, album,
genere, and track fields when reading from file.

For some reason I was only loading the library_db, and ignoring the
others. I fix this, and send out callbacks for each track loaded.

Gstreamer includes <errno.h>, which already defines several of these
symbols. I rename them to avoid namespace collisions. Perhaps a better
solution would be to use the errno.h definitions directly?

I was using CONFIG_DEBUG for these, but they really should be under

This returns a pointer to the library :: Library structure requested.
The gui will use this to display information about each path.
Signed-off-by: Anna Schumaker <schumaker.anna@gmail.com>
I track the size of each library path for display purposes. I also had
to add in a check for if a new track already exists in the db before
tagging it so updating a library should be much faster now.

Eventually these functions may have to become idle tasks, but for now I
write to disk whenever the library_db is changed and then read from disk
