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.

Scan over all tracks in the database first, and then schedule a

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.

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
initialized. That higher layer can return a pointer to be attached to
the "private data" field of the 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
also make the GUIs GstDriver static.

I was assuming that my disk returns -EIO when it enters its failed
state, but it really seems to be return -ENOENT. Let's have this code
check for any error, rather than one specific one.

One of my disks frequently returns this error, and has wiped out my
track database on more than one occasion. Let's handle this error by
disabling the library until the user tells us it is safe to use again.
