    loader: For the mini-stdio we have for lua, #define them to something else
    
    To make it easier to port lua and some of the lua modules, we have a
    series of routines to implement the stdio routines, even though we don't
    normally implement them in the boot loader. Add a comment to this effect.
    
    Also, some tools, like sanitizers and static analysis tools, make
    unwarranted assumptions about these, so #define them to a different name
    so they stop.
