tbrennan3 48411b8dbf Routing functionality complete, and working. (Have not done extensive testing, though.) 
For building, made it possible to include or exclude the routing functionality with simple changes in the main Makefile and enables in lib/Makefile and include/config.h
The Device object (device.c and .h) was extended to support the virtually routed Devices, with most of the new functions in new file gw_device.c to replace their simpler cousins in device.c.
