Added BACnetRecipient and BACnetAddressBinding codecs for EPICS application (#1163)

Browse Source 
* Added BACnetRecipient and BACnetAddressBinding encoding, decoding, ASCII conversion, comparison, and copy functions.

*  Added library specific string manipulation utilities including strcmp, strncmp, stptok, and snprintf with offset functions.

* Added test/README about verification and validation testing.
