Miroslav Lichvar 24a1a6a81e phc2sys: allow PPS loop only with system clock.
The PPS time stamps are always made by the system clock, don't allow
running the PPS loop with other clocks.

Miroslav Lichvar c5ce4ef764 phc2sys: read PHC with each PPS sample.
In the PPS loop, instead of setting the system clock from the PHC only
once on start, read PHC with each PPS sample and use the time stamp to
get the whole number of seconds in the offset. This will prevent phc2sys
from losing track of the system clock.

Also, check if the PPS is synchronized to the PHC.

Miroslav Lichvar 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.

Miroslav Lichvar 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.

Miroslav Lichvar 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.

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