Jacob Keller b8160f2760 ptp4l: add maximum offset to pi servo
this patch modifies the pi servo to add a configurable max offset (default
infinity). When ever the detected offset is larger than this value, the clock
will jump and reset the servo state. The value of this feature is for decreasing
time to stabalize when clock is off by a large ammount during late running. This
can occur when the upstream master changes, or when the clock is reset due to
outside forces. The method used to reset clock is simply to reset the pi servo
to the unlocked state.

Richard Cochran d4e761138e bugfix: use a sensible test to detect a new master.
The code to detect a new master used pointer equality using a stale
pointer within the clock instance. Instead, the clock needs to remember
the identity of the foreign master in order to correctly detect a
change of master.
