Ensure that strncpy() dest strings are terminated - Since the ERREXITS() and TRACEMSS() macros are never used internally (they are a relic of the legacy memory managers that libjpeg provided), the only risk was that an external program might have invoked one of those macros with a string longer than 79 characters (JMSG_STR_PARM_MAX - 1). - TJBench never invokes the THROW_TJ() macro with a string longer than 199 (JMSG_LENGTH_MAX - 1) characters, so there was no risk. However, it's a good idea to explicitly terminate the destination strings so that anyone looking at the code can immediately tell that it is safe.
