Might we generate llhttp .c/.h without JavaScript?

[RodrigoDornelles]

While the project is a core component of Node.js, like libuv, it is a versatile library that can be used outside the JavaScript ecosystem, such as in Julia or Luvit. Notably, llhttp pairs well with libuv, as it was designed with that integration in mind.

Non-JavaScript projects would only need JavaScript in the toolchain to generate the required .c and .h files, which can be handled with simple scripts.

C++ is a suitable choice: it offers a rich STL, high-level abstractions, and most environments with a C compiler will also have a C++ compiler, allowing generation to be orchestrated directly via CMake.

This approach keeps generator scripts maintainable and allows projects in Go, C, C++, etc., to use llhttp without introducing JavaScript into their toolchain. If integrated via CMakeLists.txt alone, it can be managed as an external project.
