Feature/apdu null length returned (#285)

* Add APDU as NULL to get BACnet type lengths. * Fix bacapp copy test to succeed * fix BACnet REAL and DOUBLE decode * Add unit test for NULL APDU encoding for length * Add unit tests for bacapp context * refactor host-n-port to hostnport.c module * fix BVLC decoder * additional unit testing for bacapp * include bacdevobjpropref module in builds * simplify bacapp snprintf to be able to return length * adjust compiler for variable-length arrays * fix bug found by scan-build Authored-by: Steve Karg <skarg@users.sourceforge.net>
