Changes from version 1.6.43 to version 1.6.44
---------------------------------------------
* Hardened calculations in chroma handling to prevent overflows, and
relaxed a constraint in cHRM validation to accomodate the standard
ACES AP1 set of color primaries.

* Removed the ASM implementation of ARM Neon optimizations and updated
the build accordingly. Only the remaining C implementation shall be
used from now on, thus ensuring the support of the PAC/BTI security
features on ARM64.

* Fixed the pickup of the PNG_HARDWARE_OPTIMIZATIONS option in the
CMake build on FreeBSD/amd64. This is an important performance fix
on this platform.
* Applied various fixes and improvements to the CMake build.
(Contributed by Eric Riff, Benjamin Buch and Erik Scholz)
* Added fuzzing targets for the simplified read API.

* Fixed a build error involving pngtest.c under a custom config.
This was a regression introduced in a code cleanup in libpng-1.6.43.
(Contributed by Ben Wagner)
* Fixed and improved the config files for AppVeyor CI and Travis CI.
