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

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.

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.

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've been excited about this! I think it'll be a better design than
what I had for Ocarina 5.x.
