this patch modifies the pi servo to add a configurable max offset (default
infinity). When ever the detected offset is larger than this value, the clock
will jump and reset the servo state. The value of this feature is for decreasing
time to stabalize when clock is off by a large ammount during late running. This
can occur when the upstream master changes, or when the clock is reset due to
outside forces. The method used to reset clock is simply to reset the pi servo
to the unlocked state.

This patch adds a flag field for setting overflag flags so that command line
options override any value in the configuration file. This will be done by
ensuring the flags set whether the config parser accepts the values specified.
This patch also streamlines the handling for the slave only command line
option, as it no longer needs special treatment.

this patch allows each port to maintain its own pod structure since it is only
used in ports. This will allow the user to configure any special settings per
port. It takes a copy of the default pod, and a future patch will allow the
configuration file to set per-port specific changes

this patch adds a support function that creates a new port based on the
current default settings and adds it to the iface list. The function returns
the index into the cfg where the port was created. If a port is attempted to
be created multiple times, future attempts just return the index

In order to support future settings which allow for the configuration of
per-port data, this patch modifies the interface name to be a static array
instead of a pointer.

Some commercial 802.1AS switches do not feel obliged to set the two step
flag. When we try to synchronize to their apparent one step sync messages,
nothing good happens. This commit adds a global option to work around the
issue.

Some of the time stamping hardware out there only recognizes layer 2
