* [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.
