Jacob Keller 31865b2589 ptp4l: change interface name into static array
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.

-v2
* Minor edit for merge with previous patch

Jacob Keller 64dcf257e3 ptp4l: pass struct interface directly instead of passing it's sub arguments
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

Jacob Keller 0499513f1e ptp4l: remove timestamping as a per-port configuration option
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.

Jacob Keller 7c501032b2 ptp4l: correct print global set functions
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.

Jacob Keller df5c071599 ptp4l: Change command line options to better match meaning
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
