Added filesystem clean bit support. This only affects fsck during a
preen (-p), and in that case the filesystem is skipped if it is clean.
A new flag "-f" for 'force' has been added which basically gives back
the old behavior of checking all the filesystems all the time. This
very closely models the behavior of SunOS and Ultrix.
