Jean-Marc Zucconi 7344a61e7b Add 2 new ioctls: WORMIOCREADSESSIONINFO and WORMIOCWRITESESSION.
These commands are required for the "Disk-At-Once" write process:
WORMIOCREADSESSIONINFO returns the length of the lead-in and lead-out areas
and WORMIOCWRITESESSION is used to send  the table of contents of the disk.
