Log Message:
upgrade_to_v319: refuse to clobber already-upgraded file bases

After smb_open(), check smb.status.total_msgs and skip any dir with
existing files; require -f on the command line to force overwrite.
Previously the tool unconditionally re-ran smb_create() on every dir,
destroying populated SMB file bases when re-run on an upgraded system.

Also remove the unused overwrite() helper and add -h/-? usage.
