If someone considers moving from `option.into_iter().flatten()` to `option.into_flat_iter()`, it may be important for performance that this iterator "specializes" methods the same way `Flatten` does, especially forwarding to underlying `fold`, etc.

We still only support `PROT_READ|PROT_WRITE`, so `mprotect` is a no-op other than validating arguments. We only implement `madvise` for the hints that can be ignored without a change in semantic (e.g. no `MADV_DONTNEED`, so it is also a no-op other than validating arguments.

This updates the rust-version file to 942ac9c.

spurious, but closing as the reversion is being tested seemingly without issue
