ci: Add ci_verify_version.sh
This program verifies the libpng source tree, expecting consistent definitions of version numbers in the C source code, in the Autoconf scripts, and in the CMake scripts. The version verification is performed as follows. (Please note that the version definitions in png.h are checked twice.) * The files png.h, configure.ac and CMakeLists.txt are checked by the ci_verify_version.sh program. * The files png.h, png.c and pngtest.c are checked by the pngtest program.
