Feature/add memap cstack usage ports (#661)

* 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.
