Subject: [PATCH] NEON implementation for Adler32
The checksum is calculated in the uncompressed PNG data
and can be made much faster by using SIMD.
Tests in ARMv8 yielded an improvement of about 3x
(e.g. walltime was 350ms x 125ms for a 4096x4096 bytes
executed 30 times). That results in at least 18% improvement
in image decoding in Chromium.
Further details at:
https://bugs.chromium.org/p/chromium/issues/detail?id=688601

Subject: [PATCH] Fix a bug when getting a gzip header extra field with
inflate().
If the extra field was larger than the space the user provided with
inflateGetHeader(), and if multiple calls of inflate() delivered
the extra header data, then there could be a buffer overflow of the
provided space. This commit assures that provided space is not
exceeded.
