Separate files needing GPL license
+ Keep apache license for now, until this is completed: https://wiki.fd.io/view/TSC/Relicensing_Procedure + Add utilities for switching license comment blocks. - They do not preserve attributes, so executable flag is lost. + Move the affected files to GPL/. + Update paths so files are executed from the new location. + Change the way scripts are started to do not require executable flag. + Employ OptionString when constructing longer command lines. + Move also PacketVerifier.py and TrafficScriptArg.py as they are linked with traffic scripts. + That means the two files are outside "resources" package tree now. + Added __init__.py files so relative imports work in new package tree. + Start traffic scripts as python modules to allow relative imports. + Once again needed because they are outside the default PYTHONPATH.

-"""This script uses T-REX stateless API to drive t-rex instance.
-
-Requirements:
-- T-REX: https://github.com/cisco-system-traffic-generator/trex-core
- - compiled and running T-REX process (eg. ./t-rex-64 -i)
- - trex.stl.api library
-- Script must be executed on a node with T-REX instance
-
-Functionality:
-1. Stop any running traffic
-2. Optionally restore reference counter values.
-3. Return conter differences.
