✘minpoll=maxpoll from 0 to 8 for RasPi 3

[Gary E. Miller]

Yo All!

Since minpoll=maxpoll=0 is starting to work, I added another test
on the RasPi 3 for that value.  No need to do so on the Xeon since
that would clearly be a bad setting.

RasPi3:

      Local Clock      Local Clock  Local Clock    PPS         PPS
Poll  Freq Offset 90%  Jitter 90%   Stability 90%  Offset 90%  Jitter 90%
0          1.0 ppm        0.65µs       8.2 ppt         1.55µs    0.76µs

2          1.1 ppm        0.08µs       2.9 ppt         2.2µs     0.20µs
3          0.5 ppm        0.18µs       1.9 ppt         3.0µs     0.56µs
4          1.12ppm        1.27µs       2.26ppt        10.3µs     4.11µs
5          1.36ppm        1.34µs       2.64ppt        11.4µs     4.43µs
6          1.4 ppm        3.3 µs       2.2 ppt        68. µs     9.7 µs
7          1.15ppm        1.14µs       1.77ppt         9.4µs     3.45µs
8          0.89ppm       39.9 µs       6.86ppt       977. µs    95.2 µs

Here poll=1 (2 sec) still looks best to me.  But poll=0 (1 sec) pretty
close.  A 1/5 second poll would be interesting, but that would require
major surgery in ntpd, so not likely anytime soon.

I wish all the data was a bit more linear.  The poll=7 data sticks out,
I'll prolly have to rerun the data sometime.  I don't think the Local
CLock Frequency Offset data is useful here, it corelates to room temp
not to poll.
