Windows Kernel support

[carlos-al]

If you try using this library directly in a Windows kernel driveryou'll see five extra imports from Kernel32.dll that shouldn't be there.

If you look at the Visual Studio solutions in zydis/msvc, you'll see that the ZydisWinKernel solution needs the BufferOverflowK library to build properly.
This can be fixed adding the following line to build.rs:
println!("cargo:rustc-link-lib=BufferOverflowK");

Resolved in 9e1528c. I also configured no-stack-protector to automatically be enabled when nolibc feature is enabled.
