2021-06-13Must use safe chunk copies due to inflateBack using the same allocation for ↵Nathan Moinvaziri
output and window. In this instance if too many bytes are written it will not correctly write matches with distances close to the window size.

2021-06-11[CHUNKMEMSET_SAFE] Precalculate "from".Mika Lindqvist
* limit len to minimum of len and left

avoid errors with optimizations enabled.
2021-06-11[CHUNKCOPY_SAFE] Fix off-by-one errorMika Lindqvist
* When chunk size was more than 8 bytes, the comparison logic failed if safe length was one less than chunk size.

2021-05-29Handle HAVE_UNISTD_H defined to 0.Paweł Wegner
FFmpeg during the configure stage generates a config.h file with ``` #define HAVE_UNISTD_H 0 ``` on windows. Then somewhere in FFmpeg's code there is: ``` #include "config.h" // FFmpeg's config.h #include <zlib.h> ``` which causes zlib.h to include unistd.h on windows. It is way easier to handle the issue here than in FFmpeg. Co-authored-by: Mika Lindqvist <postmaster@raasu.org>

2021-05-09[ARM/AArch64] More thorough testing of getauxval() macros and includesMika Lindqvist
* 32-bit ARM and AArch64 use slightly different macros for CRC32 and NEON feature bits * 32-bit ARM sometimes requires asm/hwcap.h for AT_HWCAP2
2021-05-08upgrade links to HTTPSViktor Szakats
http://infozip.sourceforge.net/ is sadly not having HTTPS access enabled. Shoutout to somebody with admin access for this project: It would be nice to enable it and thus allowing secure access to these pages via https://infozip.sourceforge.io/ . The option has been there for a while now: https://sourceforge.net/blog/introducing-https-for-project-websites/ also: - follow permanent redirects - add ending slashes

2021-04-29crc: fix three conversion warningsAaron Boxer
2021-04-29Detect hwcap flags needed for runtime detection on ARM LinuxJosh Triplett
This allows us to provide useful warning messages from cmake or configure if the system headers don't provide the necessary flags to do runtime detection.
2021-04-29Don't directly include asm/hwcap.h; fix compilation on musl aarch64Josh Triplett
sys/auxv.h includes the appropriate headers to provide the HWCAP constants, on both glibc and musl, which makes it unnecessary to include asm/hwcap.h directly. And on musl, asm/hwcap.h doesn't exist.
