Start P2P messages right away when listening after initializing.

Because of an oversight in the event code, a port will not send peer delay
request messages while in the initial listening state. This patch fixes
the issue by expanding this special, initial case.

Introduce a test for running in 802.1AS mode.

We use the follow_up_info to control behavior that is specific to the
802.1AS standard. In several instances, that standard goes against the
1588 standard or requires new run time logic that exceeds what can be
reasonably described as a 1588 profile.

Since we will need a few more run time exceptions in order to support
802.1AS, we introduce a helper function to identify this case, rather
than hard coding a test for follow_up_info, in order to be more clear
about it.

Add port logic for the 'capable' flag from 802.1AS.

This commit only provides helper functions that will implement the effect
of a port being not capable. We let the port be always 'capable' for now,
until we actually have added the details of that flag.

Add a default of 'incapable' for 802.1AS mode.

Signed-off-by: Richard Cochran <richardcochran@gmail.com>
Let a port become 'capable' according to 802.1AS.

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.

Fix fault-clearing timer being erroneously re-armed

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.

Make the fault reset interval a per-port configuration parameter.

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. ]

Stop handling file descriptor events after a port reset.

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.

phc2sys: include PTP management client.

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.

static_ptp_text is like a PTPText that includes space for the text
which makes it more convenient for ptp texts stored in the clock.
