    Disentangle do_sys_rename.

    Elide the fs-wide rename lock for single-directory renames.  This
    required changing the order of lookups, so that we know what the
    directories are before we lock the nodes.

    Clean up error branches, explain why various nonsense happens and
    what it does and doesn't do, and note some of what needs to change.
