This v2
- fixes the regression indicated in Message-ID: <20240615201144.GB4991@pb2>
by counting the number of necessary terminations for non HT code blocks with
the existing code.
- drops the commit that was recently merged.

This commit adds support for CAP and CPF markers. Decoder will exit when
encountering an illegal codestream.
It is confirmed that the decoder passes all the test cases in FATE and
ISO/IEC 15444-4.
The subject was wrong in the v5 set of patches. The v6 corrects it.

This commit adds support for CAP and CPF markers. Decoding will exit when
encountering Ilegal input codestreams.
The variable `Jpeg2000DecoderContext->HT_MAGB` has been changed to `HT_B`
according to the definition in the spec (ISO/IEC 15444-15).

, the encoded codestream size is slightly larger for a given Q value.
For example, `-flags +bitexact -i lena.pnm -q: 20 -format j2k -y tmp.j2c`
gives 13K (HEAD) and 19K (with this patch).
This commit also updates the source and reference files for affected FATE tests.
