- activate THREAD_CREATE_STACKTEST also if test_utils_print_stack_usage is used - make thread_measure_stack_free() available unconditionally - if DEVELHELP is active, call test_utils_print_stack_usage() on any thread exit - if DEVELHELP is active, call test_utils_print_stack_usage() after main for the idle thread, if that is used
