* 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.
