Sub-tile decoding: only allocate tile component buffer of the needed dimension
...
Instead of being the full tile size.
* Use a sparse array mechanism to store code-blocks and intermediate stages of
IDWT.
* IDWT, DC level shift and MCT stages are done just on that smaller array.
* Improve copy of tile component array to final image, by saving an intermediate
buffer.
* For full-tile decoding at reduced resolution, only allocate the tile buffer to
the reduced size, instead of the full-resolution size.

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.

Change 'restrict' define to 'OPJ_RESTRICT' ( #816 )
...
Visual Studio 2015 does not pass regression tests with `__restrict` so kept disabled for MSVC.
Need to check proper usage of OPJ_RESTRICT (if correct then there’s
probably a bug in vc14)
Closes #661

* Fix unsigned int overflow reported by UBSan
Please add -DOPJ_UBSAN_BUILD to CFLAGS when building with
-fsanitize=undefined,unsigned-integer-overflow
It seems clang/gcc do not allow to disable checking for block of code
other than function or file.
