Subject: [PATCH] Fix bug in deflateBound() for level 0 and memLevel 9.
memLevel 9 would cause deflateBound() to assume the use of fixed
blocks, even if the compression level was 0, which forces stored
blocks. That could result in a bound less than the size of the
compressed data. Now level 0 always uses the stored blocks bound.

Subject: [PATCH] Reject overflows of zip header fields in minizip.
This checks the lengths of the file name, extra field, and comment
that would be put in the zip headers, and rejects them if they are
too long. They are each limited to 65535 bytes in length by the zip
format. This also avoids possible buffer overflows if the provided
fields are too long.

Subject: [PATCH] s390x: vectorize crc32
Use vector extensions when compiling for s390x and binutils knows
about them. At runtime, check whether kernel supports vector
extensions (it has to be not just the CPU, but also the kernel) and
choose between the regular and the vectorized implementations.
