Check the sanity of the synchronized clock by comparing its uncorrected
frequency with the system monotonic clock. When the measured frequency
offset is larger than the value of the sanity_freq_limit option (20% by
default), a warning message will be printed and the servo will be reset.
Setting the option to zero disables the check.
This is useful to detect when the clock is broken or adjusted by another
program.

Current pi servo steps clock without any condition on start.
This patch adds a new servo option "configured_pi_f_offset". The option is similar
to configured_pi_offset but only affects in the first clock update. Therefore,
if this option is set as 0.0, we can prevent clock step on start.
The new servo option can be specified from phc2sys by using -F option.
This feature is usefull when we need to restart phc2sys without system
clock jump. Restarting phc2sys is needed to change its configuration.
changes since v2:
- manual page fix.
- also apply max_offset along with max_f_offset in servo step1.
- add a variable to check if first update is done.
changes since v1:(http://sourceforge.net/mailarchive/message.php?msg_id=31039874)
- remake as a new servo option.

The default zero offset can lead to misalignment between system clocks or wrong
time to be broadcast to the domain. Therefore we require setting offset upon
invocation.

This patch modifies phc2sys to enable the use of interface names in clock_open
rather than having to do that by hand. This enables cleaner use of the -s and -c
options as they can accept interface names. This also enables the user to set
the slave clock by network interface as well.

Add kernel_leap option for ptp4l and -x option for phc2sys to disable
setting of the STA_INS/STA_DEL bit to slowly correct the one-second
offset by servo.

Modify the pmc to allow non-blocking operation. Run it on each clock
update to have the sync offset updated from currentUtcOffset with every
other call.

Add new options to ptp4l and phc2sys to print summary statistics of the
clock instead of the individual samples.
[ RC - Fix () function prototype with (void).
- Use unsigned for sample counter.
- Fix over-zealous line breaks. ]

Add a new option to wait for ptp4l to be in a synchronized state.
Periodically check PORT_DATA_SET and wait until there is a port in
SLAVE, MASTER or GRAND_MASTER state. Also, set the default
synchronization offset according to the currentUtcOffset value from
TIME_PROPERTIES_DATA_SET and the direction of the clock synchronization.

The PPS time stamps are always made by the system clock, don't allow
running the PPS loop with other clocks.
Signed-off-by: Miroslav Lichvar <mlichvar@redhat.com>
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.
