  1. pmirror: Add option --noatime

    Open source file with O_NOATIME if option --noatime is given.
    
    If pmirror is used for backup purpose, we don't want to trigger metadata
    writes on the source filesystem. This needs to be optional, because
    O_NOATIME only works for the owner of a file or for a privileged user.
    
    As --cksum is implemented by an external command, we can't do this with
    out potentially touching the access time.
