Pitfall:
Multi-session media which bear a xorriso image for overwriteables
in their first session would get a TOC of that first image rather
than of the media.
It is not possible to distinguish a BD-RE from a single session
BD-R with an image for overwriteables. But as soon as the media
bears 2 logical tracks it cannot be overwriteable.
So count the number of tracks first.
