    test: add 119-smoothtime

commit 7f45eb7957adb9cb16a3cc296a949616570fd954
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>

    ntp: add server time smoothing
    
    Time smoothing determines an offset that needs to be applied to the
    cooked time to make it smooth for external observers. Observed offset
    and frequency change slowly and there are no discontinuities. This can
    be used on an NTP server to make it easier for the clients to track the
    time and keep their clocks close together even when large offset or
    frequency corrections are applied to the server's clock (e.g. after
    being offline for longer time).
    
    Accumulated offset and frequency are smoothed out in three stages. In
    the first stage, the frequency is changed at a constant rate (wander) up
    to a maximum, in the second stage the frequency stays at the maximum for
    as long as needed and in the third stage the frequency is brought back
    to zero.
    
    Time smoothing is configured by the smoothtime directive. It takes two
    arguments, maximum frequency offset and maximum wander. It's disabled by
    default.
