Subject: r21206: - a couple more nttrans places were a memcpy() should be used

- changed the setup array in nttrans to be a uint8 array, instead of a
  uint16 array. This makes it clearer that it is the job of the caller
  to do any byte swapping within that data
(This used to be commit fa3c9b29ae1c7c6a9bc97484cc386aeec9b5d266)
