ptp4l: create [global] INI style config header 

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.

-v2
* Forgot a "\n" in the string comparison so that global mode wasn't recognized
