There is some functionality that will always be needed for BACnet
drivers. Here we create a new bacnetutil class, built as part of the
bacnetmstp library that can handle much of the data handling and setup
a BACnet driver will need.
The idea is that any BACnet functionality needed, that is not
device-specific, should be added to this class for all drivers to use.
The intent is that all BACnet drivers will inherit from this class.
