I want to reuse as much file code as I can for cache files, but I need a
new struct since data and cache files track different properties.

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
data in case Ocarina gets killed.

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().

I'm only setting this to a static string, so it doesn't make sense to
store this as a char array. Let's use a string pointer instead.

I'm going to use this for saving album art to the right place. I moved
it into an include file to avoid duplicating code.

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.
