* Refactored and secured BACnetActionCommand codec into bacaction.c module for command object and added to bacapp module encode/decode with define for enabling and pseudo application tag for internal use.
* Simplified bacapp_data_len() and moved into bacdcode module as bacnet_enclosed_data_len() function.
* Secured ReadProperty-REQUEST and -ACK decoding.
* Removed deprecated Keylist_Key() functions from usage.
* Removed pseudo application datatypes from bacapp_data_decode() which only uses primitive application tag encoded values.
* Defined INT_MAX when it is not already defined by compiler or libc.
* Deprecated bacapp_decode_application_data_len() and bacapp_decode_context_data_len() as they are no longer used in any code in the library.
* Added BACnetScale to bacapp module. Improved complex property value decoding. Refactored bacapp_decode_known_property() function.
* Refactored and improved the bacapp_snprintf() function for printing EPICS.
* Fixed Lighting Output WriteProperty to handle known property decoding.
* Reduced MS/TP MAX_APDU to 480 from 1476 so that devices not use new MS/TP extended frame types which older routers do not understand.
* Added extra objects to STM32F4xx example to elicit edge cases in object-list for testing.
* Added memap, avstack, and checkstackusage tools to STM32F4xx Makefile and CMake builds to calculate CSTACK depth and RAM usage
* Added memap, cstack, and ram-usage recipes to stm32f10x port Makefile. Added Cmake build.
* Removed local dlmstp.c module from stm32f10x port, and used the common datalink dlmstp.c module with MS/TP extended frames and zero-config support.
* Added .nm and .su to .gitignore to skip the analysis file residue.
