f09b4bb7e3 phc2sys: remove unnecessary clock step with non-PPS loops. 
With non-PPS loops let the servo make the inital correction. Move the
code to the PPS loop and change it to use the sample filtering to reduce
the error in the initial correction.

fc1a695493 phc2sys: don't zero clock frequency on start. 
Instead of always starting at zero frequency offset, read the currently
stored value on start and pass it to the servo. As the read may silently
fail and return zero, set the clock frequency back to the read value to
make sure it's always equal to the actual frequency of the clock.

af2a4f47fb Modify PI servo to set frequency when jumping. 
Similarly to the servo in phc2sys, when clock is stepped, set
immediately also its frequency. This significantly improves the initial
convergence with large frequency offsets.

Keep the offset and the time stamp in integer nanoseconds.

5c47cbfedf Make enum transport_type match the networkProtocol enumeration 
This means no conversion is necessary between the transport_type and

issue, but will be needed for implementing the CLOCK_DESCRIPTION

ignored the actual action field in the message. This commit makes the
code look at the action field when processing the requests.
