Even Rouault f9e9942330 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.

Even Rouault 532243f1fd 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.

Stephan Mühlstrasser 8750e183c6 Moved type OPJ_BITFIELD from openjpeg.h to opj_includes.h
OPJ_BITFIELD is used only in internal headers and must not
appear in the public openjpeg.h header.

Matthieu Darbois 9f24b078c7 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

Matthieu Darbois 29313eb5f1 Fix unsigned int overflow reported by UBSan (#761)
* 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.
