  Log:
  Add a "tftp_strnlen()" routine that
  
  	1) checks to make sure that the terminating '\0' is found in the
  	   string, and throws a BoundsError exception if it isn't (TFTP
  	   packets should fit in a single frame, so if the '\0' isn't
  	   found, that's an error);
  
  	2) adds 1 to the length to include the trailing '\0';
  
  and use it to find all string lengths, so that we properly handle short
  or malformed frames.
