Changes from version 1.6.42 to version 1.6.43
---------------------------------------------

 * Fixed the row width check in png_check_IHDR().
   This corrected a bug that was specific to the 16-bit platforms,
   and removed a spurious compiler warning from the 64-bit builds.
   (Reported by Jacek Caban; fixed by John Bowler)
 * Added eXIf chunk support to the push-mode reader in pngpread.c.
   (Contributed by Chris Blume)
 * Added contrib/pngexif for the benefit of the users who would like
   to inspect the content of eXIf chunks.
 * Added contrib/conftest/basic.dfa, a basic build-time configuration.
   (Contributed by John Bowler)
 * Fixed a preprocessor condition in pngread.c that broke build-time
   configurations like contrib/conftest/pngcp.dfa.
   (Contributed by John Bowler)
 * Added CMake build support for LoongArch LSX.
   (Contributed by GuXiWei)
 * Fixed a CMake build error that occurred under a peculiar state of the
   dependency tree. This was a regression introduced in libpng-1.6.41.
   (Contributed by Dan Rosser)
 * Marked the installed libpng headers as system headers in CMake.
   (Contributed by Benjamin Buch)
 * Updated the build support for RISCOS.
   (Contributed by Cameron Cawley)
 * Updated the makefiles to allow cross-platform builds to initialize
   conventional make variables like AR and ARFLAGS.
 * Added various improvements to the CI scripts in areas like version
   consistency verification and text linting.
 * Added version consistency verification to pngtest.c also.
