    .                    packet-tftp.c 
  Log:
  Add a new "tvb_strsize()" routine, which finds the size of a
  NUL-terminated string, starting at a given offset.  The size includes
  the terminating NUL.  If it doesn't find the terminating NUL, it throws
  the appropriate exception, as either there's no terminating NUL in the
  packet or there is but it's past the end of the captured data in the
  packet.
  
  Use that routine in the TFTP dissector.  As it throws an exception if
  the string isn't NUL-terminated, we can just use "%s" to print option
  strings; we don't need to use "%.*s" with a string length.
