Even Rouault ac375ac9f5 Partial revert BPC related check of #975 (#979)
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.

Even Rouault 92114694a4 Slight improvement in management of code block chunks
Instead of having the chunk array at the segment level, we can move it down to
the codeblock itself since segments are filled in sequential order.
Limit the number of memory allocation, and decrease slightly the memory usage.

Even Rouault ca34d13e76 Decoding: do not allocate memory for the codestream of each codeblock
Currently we allocate at least 8192 bytes for each codeblock, and copy
the relevant parts of the codestream in that per-codeblock buffer as we
decode packets.
As the whole codestream for the tile is ingested in memory and alive
during the decoding, we can directly point to it instead of copying. But
to do that, we need an intermediate concept, a 'chunk' of code-stream segment,
given that segments may be made of data at different places in the code-stream
when quality layers are used.

With that change, the decoding of MAPA_005.jp2 goes down from the previous
improvement of 2.7 GB down to 1.9 GB.
