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.
