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.

Current date stored in nanoseconds doesn't fit in 64-bit double format.
Keep the offset and the time stamp in integer nanoseconds.

This means no conversion is necessary between the transport_type and
the networkProtocol field of the PortAddress struct. Not currently an
issue, but will be needed for implementing the CLOCK_DESCRIPTION
management TLV.
Previously if a command's full name was a prefix of another command
then parse_id would return AMBIGUOUS_ID. This was a problem for the
TIME and various TIME_* messages.
The code previously treated all supported request as 'get' actions and
ignored the actual action field in the message. This commit makes the
code look at the action field when processing the requests.

Reforming the data structure in this way will greatly simplify the
implementation of the management message for this data set.

The phyter offers one step sync transmission, but it alters the UDP
checksum by changing the last two bytes, after the PTP payload. While this
is only standardized for IPv6, we will go with it for IPv4 as well, since
the phyter is the only hardware out there.

The Linux kernel supports a hardware time stamping mode that allows
sending a one step sync message. This commit adds support for this mode
by expanding the time stamp type enumeration. In order to enable this
mode, the configuration must specify both hardware time stamping and set
the twoStepFlag to false.
We still do not support the one step peer delay request mechanism since
there is neither kernel nor hardware support for it at this time.
