Anna Schumaker a9dae134d0 database: Store pointers 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.

Anna Schumaker 81f3ef458f database: Each DatabaseEntry should know its id
This will let me set up a Track class that has pointers to the
corresponding artist, album and genre information without needing to
know their IDs directly.  Having this information available means I
won't need to keep a "join struct" when doing lookups - instead I can
return a pointer to a Track class that already knows everything.

Anna Schumaker 1b34a9a8a0 index: Update the index design
I updated the design and rewrote the unit tests.  This creates something
more consistent with how I ended up using the index.

Anna Schumaker 959cac0fe1 Database: Update design for database entries
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.

Anna Schumaker a50d8f6e0a database: Allow templated keys to the database index
This allows me to have a std::pair<> as a key if needed.

Anna Schumaker 97d889531a index: Remove the index class
This patch updates the design so indexes are built upon databases using
a special IndexEntry.  I also updated the tests/index/ test to match
the new system, but I have not updated filter or group tests yet.

Anna Schumaker 50a7c3dae6 database: Add funcions for database iteration
A database may have invalid rows.  If this is the case, then the next()
function needs to return the id of the next valid row.  I'm aware that
this could get horribly inefficient on large DBs with many invalid rows.
I don't expect people to delete large chunks of music all at once, but a
defragment tool is on my "todo" list for a future Ocarina version.

I don't have the DatabaseEntry base class yet, but I will soon!

Anna Schumaker fee08b1f94 database: Begin database code
I've been excited about this!  I think it'll be a better design than
what I had for Ocarina 5.x.
