If a symlink, device, special-file, or hard-linked file is replacing an existing non-directory, the new file is created using a temporary filename and then renamed into place. Also changed the handling of a cluster of hard-linked symlinks/devices/special-files to always ensure the first item in the cluster is correct, since it doesn't really save any significant work to try to find an existing correct item later in the cluster to link with.
