Log Message:
Check the superblock version field, and refuse to mount the filesystem
if the version number is higher than we know about.  This allows, e.g.,
changes in the format of the ifile, segment size restrictions and boundaries,
etc., which would not affect existing fields in the superblock, but which
would drastically affect the filesystem, to be smoothly integrated at a
later date.
