360ebed1fa errors: Rename error codes
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?

ff0fead24e database: Mark new entries valid based on id
I was using _size as an index into the database, but _size represents
the total number of valid rows and not the id of the new item.  If a row
is deleted _size will decrease and the wrong entries will be marked
valid.

This allows me to have a std::pair<> as a key if needed.

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.

f0533ef663 database: Make all databases unique
I require entries to have a "primary key" that is stored in a map to
make it easy to find database rows by key.

8ccbad20cc database: Mark rows valid when inserted
It doesn't make sense to need to set this value outside of the database
code like I had been doing.  So when a new row is inserted mark it as
valid right away.

79d592ed64 database: Add a function for printing
Other tests may need to print out a database.  To make this easier I've
added a print() function to the base database class.  This function will
only exist when CONFIG.TEST == True, so don't use it outside of testing!

dd92ee853f database: Add a way for databases to have unique keys
The library will need databases that have unique values (such as the
artist or album tables).  This patch adds support for that in my
existing database code.

13313482d4 database: Make read() and write() functions for database entries
I had planned on using the stream operator for my database class but
this created some crazy compiler error that I was having difficulty
figuring out.  I decided to take the easy route for now and instead
create read() and write() functions that do exactly the same thing.

a5891a3338 database: Implement quick removal of items
Items will be marked "invalid" rather than directly removed from the
database.  This make it easier, since I won't need to reassign IDs to
every database item after the removed one.

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.
