Okay, fixed the problems I could find on my own, so this should be ready for review. |

These methods enable looking up mutable references to several entries in a table or map at once. They make use of the min_const_generics feature, which is available without a feature gate on recent nightly — but not yet stable — rustc. Hence everything added here is behind `#[cfg(feature = "nightly")]`. This also removes an unnecessary `unsafe` annotation for `Bucket::as_ptr`.
