This is useful to better isolate `unsafe` code. Once all unsafe calls are wrapped we can enable the Rust warning. This also explicitly disables the warning for generated code, which is a much more difficult task. After this change there are 211 warnings left in `script_bindings`. Testing: This should not change behavior and is thus covered by existing tests. Signed-off-by: Martin Robinson <mrobinson@igalia.com>
