The current raw block drvice code fakes a TOC with one track covering
the entire disc.  With this patch it attempts to read the TOC from a
cdrom device and make that information available to the ide driver
when the guest issues an ATAPI READ TOC/PMA/ATIP type 0 (read TOC)
command.

I recently sent a patch to add this for linux but then I thought of a
better way to do it.
I the TOC was stored in a struct somewhere, built when starting (or
changing media) using either .toc, .cue, real CD or maybe even a list
of track files this would allow to use such methods. Would be really
useful for me actually to be able to use a list of tracks but
generating toc/cue is quite easy.
