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.

Encoder: fix packet writing of empty sub-bands (#891, #892)2017-06-12T16:37:50ZEven Rouaulteven.rouault@spatialys.com2017-06-12T10:23:55Zurn:sha1:73d1510d473b7dcfccfdee57e0e511e6791d5091
There are situations where, given a tile size, at a resolution level,
there are sub-bands with x0==x1 or y0==y1, that consequently don't have any
valid codeblocks, but the other sub-bands may be non-empty.
Given that we recycle the memory from one tile to another one, those
ghost codeblocks might be non-0 and thus candidate for packet inclusion.

There were a number of defects regarding when and how the termination of
passes had to done and the computation of their rate.
