Description

PR https://github.com/OISF/suricata/pull/5903/checks?check_run_id=1960895136 failed tests on Windows because of a type mismatch (u8 <-> i32), there was no warning/error from the compiler or cbindgen about this. Add a warning for such cases.
Jason says, "The compiler or cbindgen can't warn us here, but we could look at bindgen to create the extern statements.. However, not sure if it will define these function types for it, it generates more traditional extern statements like https://github.com/OISF/suricata/blob/681f95e80a885e56493b0994b22539b0bfbfa8a5/rust/src/core.rs#L224"

Jason says there is no reasonable fix without moving to bindgen.

Jason suggested that only manual reviews can work in this case. It may be possible with bindgen (https://github.com/rust-lang/rust-bindgen) but we cannot do that right now.
