- consoleDebugInit now lives in a separate source code file - The devoptab for debugDevice_CONSOLE is now loaded weakly, so that normal console code isn't linked in by explicit means - consoleInit no longer sets up stderr. If stderr to console is desired, explicitly use consoleDebugInit(debugDevice_CONSOLE) - This change makes it possible to use debugDevice_SVC without linking in the entire console runtime, which in turn also enabled default native window handling (and this can be undesirable)
