The track database now tallys total play count and unplayed track count,
so we can use this information for calculating averages. I also changed
the least played tracks playlist to allow tracks with play count equal
to the average.

This function returns the average count of tracks that have been played,
and not the average count of all tracks.

I no longer need these now that the queue is using the glib
g_random_int_range() function.

Using somebody else's library is probably better than relying on my own
random number function.

I need to do this for temporary queues in addition to the collection for
bolding to work properly.

This function is similar to queue_remove(), except the remove can be
prevented if qop_erase() returns false.

We don't need different operations for each queue. If we store this
then a higher layer doesn't need to keep passing the same structure over
and over again.

Enabling all queues by default, even ones read from disk, is incorrect
as it leads to all queues getting reenabled when restarting Ocarina.

This function is used to notify a higher layer that a queue is being
deinitialized. The higher layer should then clean up any state
associated with that queue.

This function is used to notify a higher layer that a queue has been

the "private data" field of the queue.

It's better to have a single function loading tracks and adding them to
the history queue.

6.4.8 changed how random tracks are selected, but never updated the unit
test. This patch fixes the unit test, and makes a few changes to make
sure the right tracks are getting selected.

The GUI needed an extra function to do this manually, which means it's
something that core should do instead.

This replaces the is_playing() function of the AudioDriver class. I can

Dividing queue size by 3 seems to give a better distribution of tracks,
but only for a large set of tracks (such as the entire collection).
let's skip the division if the queue only has a small number of tracks.
