+ Improve the state machine logging in the time server so we have some
visibility into why it is doing the things it is doing.
+ Also, reject sync responses we receive from IP addresses which are
not our current master. Given the poor quality of the AAH WiFi
network right now, we are thrashing a whole lot and can actually get
into a state where this starts to happen. Its easy to check and
reject invalid responses, so do so.

Client's of Masters who disappear before the client has processed even
one timesync response should not enter the Ronin state. Since they
have never synced to the old Master's timeline, by becoming Ronin they
run the risk of defeating other new Ronin's in the master election,
even though they don't have any idea what time it is on the old
Master's timeline and therefore are unsuitable to serve as the new
Master. Instead, they should transition to the Initial state, where
other new Ronins (who do know what time it is) have the chance to step
in and serve as master of the old timeline. If there are no other
Ronin who can do the job, then the old timeline is dead and by
transitioning to Initial, a new one will be generated.
