    Improve handling of missing '.' and '..' in UFS directories.

    The UFS filesystem expects to find '.' and '..' as the first two entries
    in a directory. The kernel's UFS name cache can become quite confused
    when these two entries are not present as the first two entries.

    Prior to this change, when the fsck_ffs(8) utility detected that
    '.' and/or '..' were missing, it would report them, but only offered
    to replace them if the space at the beginning of the directory was
    available. Otherwise it was left to the system administrator to
    move the offending file(s) out of the way and then rerun fsck_ffs(8)
    to create the '.' and '..' entries.

    With this change, fsck_ffs(8) will always be able to create the '.'
    and/or '..' entries. It moves any files in the way elsewhere in the
    directory block. If there is no room in the directory block to which
    to move them, they are placed in the lost+found directory.
