Teach fsck about snapshot files. These changes should have no
effect on operation of fsck on filesystems without snapshots. If you get compilation errors, be sure that you have copies of /usr/include/sys/mount.h (1.94), /usr/include/sys/stat.h (1.21), and /usr/include/ufs/ffs/fs.h (1.16) as of July 4, 2000 or later.
