1. Top (main) makefile defines build configuration variables and export them for sub-makes to use. BAC_ROUTING is defined here - is has been removed from config.h.
2. A new makefile has been added in demo subdirectory. It builds the demo applications. NOTE: the 'ports' target is not build.
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.
The work is not complete yet; this is an interim checkin. Ultimately the device.c file will be merged with the regular one or the deltas will be separated into some other file.
