    device: Restart verification if error is "retry" · 704c19b8
    Bastien Nocera authored
    fprintd's API docs say that "retry" errors for verification
    "the verification is still ongoing" and that "[the] user should retry
    scanning their finger.
    
    Unfortunately, retry errors are fatal in libfprint. Make fprintd restart
    operations when "retry" is the error for either identification or
    verification purposes.
    
    We need to also make sure that a "*Stop" D-Bus call will return as
    normal if called while we're stopping a verification or identification
    in order to restart it.
    
    Closes: #22
