    upstream: adjust ftruncate() logic to handle servers that reorder
    
    requests.
    
    sftp/scp will ftruncate the destination file after a transfer completes,
    to deal with the case where a longer destination file already existed.
    We tracked the highest contiguous block transferred to deal with this
    case, but our naive tracking doesn't deal with servers that reorder
    requests - a misfeature strictly permitted by the protocol but seldom
    implemented.
    
    Adjust the logic to ftruncate() at the highest absolute block received
    when the transfer is successful. feedback deraadt@ ok markus@
