This PR significantly reworks the way glslang is versioned. Instead of committing changes to the `GLSLANG_MINOR_VERSION` define in `glslang/Public/ShaderLang.h`, and using `make-revision` to generate `GLSLANG_PATCH_LEVEL` in `glslang/Include/revision.h`, all version information is now derived from the new `CHANGES.md` file. `CHANGES.md` acts as the single source of truth for glslang version information, along with a convenient place to put all release notes for each notable change made. `CHANGES.md` is parsed using the new `build_info.py` python script. This script can read basic template files to produce new source files, which it does to read the new `build_info.h.tmpl` to generate (at build time) a glslang private header at `<build-dir>/include/glslang/build_info.h`. I've written generators for each of the CMake, Bazel, gn, and `Android.mk` build scripts. The new version code conforms to the Semantic Versioning 2.0 spec. This new version is also used by the CMake rules to produce versioned shared objects, including a major-versioned SONAME. New APIs: --------- * `glslang::GetVersion()` returns a `Version` struct with the version major, minor, patch and flavor. Breaking API changes: --------------------- * The public defines `GLSLANG_MINOR_VERSION` and `GLSLANG_PATCH_LEVEL` have been entirely removed. * `glslang/Public/ShaderLang.h` and `glslang/Include/revision.h` have been deleted. * Instead, `<build-dir>/include/glslang/build_info.h` is created in the build directory, and `<build-dir>/include` is a CMake `PUBLIC` (dependee-inherited) include directory for the glslang targets. * `<build-dir>/include/glslang/build_info.h` contains the following new #defines: `GLSLANG_VERSION_MAJOR`, `GLSLANG_VERSION_MINOR`, `GLSLANG_VERSION_PATCH`, `GLSLANG_VERSION_FLAVOR`, `GLSLANG_VERSION_GREATER_THAN(major, minor, patch)`, `GLSLANG_VERSION_GREATER_OR_EQUAL_TO(major, minor, patch)`, `GLSLANG_VERSION_LESS_THAN(major, minor, patch)`, `GLSLANG_VERSION_LESS_OR_EQUAL_TO(major, minor, patch)` * The CMake install output directory contains a copy of `build_info.h` at: `include/glslang/build_info.h` * Python3 is now always required to build glslang (likely always required for transitive dependency builds).
