Fixed the run-time discovery of MIPS MSA hardware.

Fixed an off-by-one error in the function png_do_check_palette_indexes,

which failed to recognize errors that might have existed in the first column of a broken palette-encoded image. This was a benign regression accidentally introduced in libpng-1.6.33. No pixel was harmed. (Contributed by Adam Richter; reviewed by John Bowler)

Fixed, improved and modernized the contrib/pngminus programs, i.e.,

png2pnm.c and pnm2png.c

Removed old and peculiar portability hacks that were meant to silence

warnings issued by gcc version 7.1 alone. (Contributed by John Bowler)

Fixed and modernized the CMake file, and raised the minimum required

CMake version from 3.1 to 3.6. (Contributed by Clinton Ingram, Timothy Lyanguzov, Tyler Kropp, et al.)

Allowed the configure script to disable the building of auxiliary tools

and tests, thus catching up with the CMake file. (Contributed by Carlo Bramini)

Fixed a build issue on Mac.

Moved the Autoconf macro files to scripts/autoconf. Moved the CMake files (except for the main CMakeLists.txt) to

scripts/cmake and moved the list of their contributing authors to scripts/cmake/AUTHORS.md

Updated the CI configurations and scripts. Relicensed the CI scripts to the MIT License. Improved the test coverage.
