Replace all uses of sprintf() with snprint()

Replace all uses of sprintf() with snprint()

- sprintf() does not limit the length of the character string when writing
  to a buffer and may result in buffer overflow
- snprintf() requires the maximum write length as a parameter. When the
  maximum length supported is smaller than the reserved buffer length,
  the call will not result in buffer overflow
