Merged requested to merge UpgradedStackUsageChecker into master
The orchestrator submodule was dug up from the coffins, moved to Python3, and enhanced with Pylint/Mypy/Flake8 checks.
In addition, it was modified to support external cross-prefixes (to be used e.g. with EDISOFT toolchains).
$ ./checkStackUsage.py -c sparc-rtems4.8- someELF
Speaking of EDISOFT, the script was also enhanced with a hardcoded 'ignoring' of the pseudo-recursiveness of rtems_clock_get. For details, look at the code.
