* [antonin] changed remaining "WIN32" to "_WIN32"
! [antonin] libopenjpeg has no more dependency on LCMS lib. Everything concerning color (icc profile, conversion to rgb, etc) has been put outside libopenjpeg and is used in j2k_to_image.c and mj2_to_frames.c.
- [antonin] removed "opj_convert{.c,.h}"
+ [antonin] added a directory "common/" that contains "getopt{.c,.h}" (previously in "codec/compat").
+ [antonin] added files "color{.c,.h}" in "common/" that define the code for icc profile management and sycc_to_rgb conversion
+ [antonin] added "common/format_defs.h" that contains common definitions used in image_to_j2k, j2k_to_image, j2k_dump.

Fixed openjpeg.c for proper initialization of codec context structures (dinfo in opj_create_compress() and opj_create_decompress(). Bug fix suggested by Andrey V. Kiselev
...
Clean up of opj_aligned_malloc(), to just forgo the use of posix_memalign(), as apparently memalign() is what is working better for everyone. Patch by Callum.

In image.c, changed the opj_image_create0() memory allocation from malloc() to calloc() in order to avoid segfaults when freeing the memory allocated for the coding of bad images. Thanks to Christopher Layne for this improvement.

Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest allocations, because it contains a bunch of static buffers. This also makes it a major source of cache thrashing. This patch allocates the buffers from the heap, and dynamically sizes them in the decoder. I have not yet managed to dynamically size them in the encoder, getting the decoder to do it was tricky enough... I also split opj_tcd_cblk_t into separate encode and decode versions. A lot of fields were not used by both, so this cuts its size even further.

Patch by Callum Lerwick. This patch rearranges the largest memory allocations so they're allocated as late as possible, and freed as soon as possible. This cuts memory usage by about half on two large test images.

Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c

Patch by Dzonatas and Callum Lerwick. Fp/vectorization patch which basically converts most of the irreversible decode codepath to floating point, eliminating a few rounds of int/fp conversion, resulting in a vast performance improvement, and an increase in accuracy.

Changed the way the image structure is allocated when the decoding parameters include some resolutions to discard. This should have a significant impact for the decoding of huge images when some resolutions are discarder (-r parameter)
...
Warning: The output image size is now reduced when discarding resolutions !
