Add new time stamp processing modes to return raw delay and offset based
on the raw delay instead of the long-term filtered delay, and to return
also a weight of the sample. The weight is set to the ratio between the
two delays. This gives smaller weight to samples where the sync and/or
delay messages were delayed significantly in the network and possibly
include a large error.

This patch adds a configuration option that allows running a boundary clock
using "just a bunch of devices". Normally each port is probed to make sure
they all share the same PTP hardware clock, but this option will allow a
heterogeneous collection of devices, should the user really want it.

When peer delay is < min_neighbor_prop_delay the port is flagged
as non 802.1AS capable. min_neighbor_prop_delay defaults to -20ms.

Commit e425da2f inadvertently enabled the announce timer on the UDS port,
causing it to continually reopen the socket when in slave mode. This patch
fixes the issue by passing zero in the 'span' field of the new function,
set_tmo_random, which disables the timer again.

Add new options delay_filter and delay_filter_length to select the
filter and its length. They set both the clock delay filter and the port
peer delay filter. The default is now moving median with 10 samples.

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.

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.

New clock options should go into 'struct default_ds' so that we can avoid
growing clock_create indefinitely.

Adds struct containing clock description info that will be needed for
USER_DESCRIPTION and CLOCK_DESCRIPTION management messages.

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. ]

This commit gets the project off to a good start. The header files provide
