Create a new 32-bit fs_flags word in the superblock. Add code to move
the old 8-bit fs_old_flags to the new location the first time that the filesystem is mounted by a new kernel. One of the unused flags in fs_old_flags is used to indicate that the flags have been moved. Leave the fs_old_flags word intact so that it will work properly if used on an old kernel. Change the fs_sblockloc superblock location field to be in units of bytes instead of in units of filesystem fragments. The old units did not work properly when the fragment size exceeeded the superblock size (8192). Update old fs_sblockloc values at the same time that the flags are moved.
