I don't think it makes sense that callers of file_open() are expected to
check the file version after opening. This should be something handled
by the file code so we can print a consistent error message.

I want to be able to print any message as an error message without
relying on errno. Let's handle this by introducing REPORT_ERRNO() to
look up the right error message for a given errno.

And then rename the temporary file when closed. This protects users

There are enough differences in the read and write paths that
__file_open_common() was still trying to account for. Let's make a
simpler wrapper around g_fopen() and move differing code into
__file_open_read() and __file_open_write().

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.

This function is similar to queue_remove(), except the remove can be

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

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

"Banning" a track is a bit harsh. Let's talking about hiding tracks
