found a bug in tcd.c that was preventing to find the correct threshold in tcd_rateallocate.c for high-precision images. Applied a temporary patch but a better solution should be found.

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 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)

Changes proposed by Mathieu Malaterre from the GDCM project... Thanks a lot Mathieu
...
- '//' replaced by '/* */'
- inclusion of int.h in int.c
- inclusion of j2k.h in int.h in order to export symbols
- adding (void) var when a variable is declared but not used
- some explicit cast
- CLOCKS_PER_SEC is declared as float in bcc55, so there is a need to cast it to int for the modulo operation
- some variables changed from float -> double
