Summary
We consider `as_slice` and `as_slice_mut` unsound because: the pointer with any bit patterns could be cast to the slice of arbitrary types. The pointer could be created by unsafe new and deprecated `from_parts`. We consider that `from_parts` should be removed in latest version because it will help trigger unsoundness in `as_slice`. With new declared as unsafe, `as_slice` should also declared as unsafe. This was patched in by marking two functions as `unsafe`.
