First attempt to clean-up Makefiles.

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.
