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.

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.

Add a batch mode, where the commands are taken from the command line

When a port makes a transition from one state to another, it resets all of
the message timers. While this is the correct behavior for E2E mode, the
P2P mode requires sending peer delay requests most of the time.
Even though all the other timer logic is identical, still making an
exception for P2P mode would make the code even harder to follow. So this
patch introduces two nearly identical helper functions to handle timer
reprogramming during a state transition.

Now that there are clock/port_management_set functions, the IDs that
GETs are handled for, like DEFUALT_DATA_SET, still need to be in the
case for sending NOT_SUPPORTED errors.

Adds port_management_send_error and clock_management_send_error to
avoid repeatedly checking the result of port_managment_send_error and
calling pr_err if it failed. Future patches send more mgmt errors so
this will avoid repeated code.

There really is no such state, but there probably should have been one.
In any case, we do have one just to make the code simpler, but this should
not appear in the management responses. This patch fixes the issue by
covering over our tracks before sending a response.

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.

If the port resets itself after detecting a fault, then the polling events
for that port are no longer valid. This patch fixes a latent bug that
would appear if a fault and another event were to happen simultaneously.

A timeout of 15 seconds is not always acceptable, make it configurable.
By popular consensus, instead of using a linear number of seconds, use
the 2^N format for the time interval, just like the other intervals in
the PTP data sets. In addition to numeric values, let the configuration
file support 'ASAP' to have the fault reset immediately.
[RC - moved the handling of special case tmo=0 and added a break out
of the fd event loop in case the fds have been closed.
- changed the linear seconds option to log second instead.
- changed the commit message to reflect the final version. ]

Arm the fault-clearing timer only when an event causes a port to change state
to PS_FAULTY. Previously, if poll() returned because of an fd event other than
the fault-clearing timeout, the fault clearing timer would re-arm for
each port in PS_FAULTY state.

This patch implements the capable flag as follows.
1. After calculating the neighbor rate, we are capable.
2. If we miss too many responses, we are incapable.
3. If we get multiple responses, we throw a fault,
and so we are also incapable.
