Define a new build mode DEBUG_STRESS. This will be used to stress some code parts which cannot be reproduce easily with an alternative suboptimal code. First, a global <mode_stress> is set either to 1 or 0 depending on DEBUG_STRESS compilation. A new global keyword "stress-level" is also defined. It allows to specify a level from 0 to 9, to increase the stress incurred on the code. Helper macro STRESS_RUN* are defined for each stress level. This allows to easily specify an instruction in default execution and a stress counterpart if running on the corresponding stress level.
