this patch enables the configuration file to define per-port specific
configuration options via the use of simple INI style syntax with headings for
each port created via [device_name] syntax
[ RC - correct scanning of the port string
- remove '=' from scan format string ]

This patch creates a global heading for an INI style configuration file. The
parser allows the default state to be global without the header as well as to
use global. A future patch will enable per-port configuration settings.

this patch causes interfaces to be built after the options have finished
scanning rather than during option parsing. This removes the ability to
specify on the command line separate transport, or dm modes for each port.
Instead this functionality will be added in a follow-on patch via the
configuration file

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

the port_open function takes a large number of command options, a few of which
are actually all values of struct interface. This patch modifies the port_open
call to take a struct interface value instead of all the other values. This
simplifies the overall work necessary and allows for adding new port
configuration values by appending them to the struct interface

The current code for the timestamping mode does not allow interfaces to have
separate timestamping modes. This is (probably) due to hardware timestamping
mode being required on all ports to work properly.
This patch removes the timestamping field in the struct iface, and makes it a
clock variable which is really what the mode does anyways. Ports get passed
the timestamping mode but no longer appear as though they are separate.

this patch updates the global set functions to allow the user to set the
proper value instead of only being allowed to enable (or disable) a particular
feature. The new patch allows the function to specify exactly what they want
the value to be.
This patch also clarifies what -q and -v do by removing mention of quiet mode
and verbose mode. It is easy for a user to confuse and assume that -q disables
-v when this is not true.

modify the command line options to make better sense of what each one does.
Ignore previous restriction on disallowing different options on the same
letter with different case.
the purpose of this patch is to simplify the meaning of some very confusing
options (-z for legacy, -r for hardware timestamps, -m for slave)
While there are legacy issues involved with changing options around, it is
important for the user to be able to quickly understand and make fewer
mistakes regarding the various command line options
