Changed the API to pass the NPDU data down through the datalink layer in order to make the dlmstp work since it needs data-expecting-reply information. Of course, this affected all the demos, all the unit tests, and most of the demo handlers. Corrected some TSM leaks in confirmed messages. Refactored the AtomicReadFile and AtomicWriteFile demos by moving the Send_ functions to the demo/handlers directory and using the s_whois common handler. Added some common defines for the BACnet version and revision since several modules were using the info. Hopefully I didn't break too many things.
