 * All these scary macro are about three goals:
 * 1) performance optimization: real ECU hardware firmware should access configuration via direct global variable access without any pointers
 * 2) design enforcement: unit tests should access configuration via pointers, NOT via global variables
 * 3) design enforcement: user code should take special considerations in order to access specific group of configuration and not have access to complete configuration by default
