Extend the clock_utc_correct function to handle leap seconds announced
in the time properties data set. With software time stamping, it sets the
STA_INS/STA_DEL bit for the system clock. Clock updates are suspended
in the last second of the day.

Update the currentUtcOffset and leap61/59 values at one minute
interval. When a leap second is detected, set the STA_INS/STA_DEL
bit for the system clock.

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.

This patch also changes port_capable() to reset the port's nrate every time asCapable changes
from true to false.

If messages are not freed, it is possible (with purposely crafted traffic) to trigger
a peer delay calculation which will use message's data from the previous round.

The 'struct ptp_message" includes a 64 bit integer field, ts.pdu.sec,
and this must be aligned to an eight byte boundary for armv5 machines.
Although the compiler puts the field at the right offset, we spoil this
by packing the struct with 20 bytes of head room. This patch fixes the
issue by realigning the message buffer.

Many of the single field management messages have just two bytes, one for
the data value and one for padding. This patch adds a structure that can
be used for all of these management IDs.

Modifies existing structs changing Octet *foo -> Octet foo[0] and
marks them PACKED so the message buffer can be cast to the structs.

These flexible TLVs don't need to be represented as a single packed
struct directly in the message buffer. Instead a separate struct
contains pointers to the individual parts of the TLV in the message
buffer. The flexible TLV can only be the last TLV in a message.

New clock options should go into 'struct default_ds' so that we can avoid

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. ]

If the delay is known, print it together with the offset and frequency.
Remove the time stamp from the output to fit it into 80 chars.

Change the label of the frequency offset in the clock messages printed
by ptp4l and phc2sys from "adj" to "freq" to indicate it's a frequency
value.
Also, modify clock_no_adjust() to print the frequency offset instead of
the ratio and use PRId64 instead of lld to print int64_t values.

The clock_sync_interval() function is called when logSyncInterval
changes from zero. Call it also when the clock is created to have
fest.max_count set accordingly to freq_est_interval even with zero
logSyncInterval.

Before calculating the clock drift in the PI servo, make sure
the first sample is older than the second sample to avoid getting
invalid drift or NaN.
