Partial revert BPC related check of #975 (#979)

2017-08-09T09:34:08Z

PR #975 introduced a check that rejects images that have different bit depth/sign per compoment in SIZ marker if the JP2 IHDR box has BPC != 255 This didn't work properly if decoding a .j2k file since the new bit added in opj_cp_t wasn't initialized to the right value. For clarity, tThis new bit has also been renamed to allow_different_bit_depth_sign But looking closer at the code, it seems we were already tolerant to inconsistencies. For example we parsed a JP2 BPCC box even if BPC != 255 (just a warning is emitted) So failing hard in opj_j2k_read_siz() wouldn't be very inconsistent, and that alone cannot protect against other issues, so just emit a warning if BPC != 255 and the SIZ marker contains different bit depth/sign per component. Note: we could also check that the content of JP2 BPCC box is consistant with the one of the SIZ marker.

Fix assertion / memory leak in opj_j2k_merge_ppt() on corrupted images (#939)

2017-07-26T17:49:38Z

Fixes issue on id:000020,sig:06,src:001958,op:flip4,pos:149 that has two SOT markers for the same tile with the same tile part number, causing opj_j2k_merge_ppt() to be called several times.

MQC/RAW decoder: use an artificial 0xFF 0xFF terminating marker.

2017-06-02T16:24:07Z

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.
