Sebastian Rasmussen f3ee448815 openjp2/j2k: Validate all SGcod/SPcod/SPcoc parameter values.
Previously the multiple component transformation SGcod(C)
and wavelet transformation SPcod(H)/SPcoc(E) parameter
values were never checked, allowing for out of range values.

The lack of validation allowed the bit stream provided in
issue #1158 through. After this commit an error message
points to the marker segments' parameters as being out of
range.

input/nonregression/edf_c2_20.jp2 contains an SPcod(H) value
of 17, but according to Table A-20 of the specification only
values 0 and 1 are valid. input/nonregression/issue826.jp2
contains a SGcod(B) value of 2, but according to Table A-17
of the specification only values 0 and 1 are valid.
input/nonregression/oss-fuzz2785.jp2 contains a SGcod(B)
value of 32, but it is likewise limited to 0 or 1. These test
cases have been updated to consistently fail to parse the
headers since they contain out of bounds values.

This fixes issue #1210.

Hugo Lefeuvre ca16fe5501 convertbmp: fix issues with zero bitmasks
In the case where a BMP file declares compression 3 (BI_BITFIELDS)
with header size <= 56, all bitmask values keep their initialization
value 0. This may lead to various undefined behavior later e.g. when
doing 1 << (l_comp->prec - 1).

This issue does not affect files with bit count 16 because of a check
added in 16240e2 which sets default values to the color masks if they
are all 0.

This commit adds similar checks for the 32 bit case.

Also, if a BMP file declares compression 3 with header size >= 56 and
intentional 0 bitmasks, the same issue will be triggered in both the
16 and 32 bit count case.

This commit adds checks to bmp_read_info_header() rejecting BMP files
with "intentional" 0 bitmasks. These checks might be removed in the
future when proper handling of zero bitmasks will be available in
openjpeg2.

full or reduced resolution, use of decode area or not.
