010ae27471
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.

Fixed a copy-and-paste type assignment error (bool instead of int) in the JPWL section of decoder parameters structure in openjpeg.h; minor type-casting in jpwl_lib.c. As a result, now OPJViewer should run correctly when built against the most current SVN trunk of LibOpenJPEG.lib

Use of OPJ_PATH_LEN (defined as 4096) to be the maximum allowed size for filenames instead of MAX_PATH which is not always defined. This caused some programs using OpenJPEG to crash. Modifications in openjpeg.h j2k_to_image.c and image_to_j2k.c
