    stdio: Disable USE_XPRINTF envar.
    
    As xprintf has not kept up with our standard printf(3) implementation,
    it is becoming increasingly dangerous to continue to allow it to take
    over if USE_XPRINTF is defined.  Remove that code, while still allowing
    applications which know about xprintf to select it.
