MQC/RAW decoder: use an artificial 0xFF 0xFF terminating marker.
...
This saves comparing the current pointer with the end of buffer pointer.
This results at least in tiny speed improvement for raw decoding, and
smaller code size for MQC as well.
This kills the remains of the raw.h/.c files that were only used for
decoding. Encoding using the mqc structure already.

Reduce number of occurrences of orient function argument

This is essentially used to shift inside the lut_ctxno_zc, which we
can precompute at the beginning of opj_t1_decode_cblk() /
