This branch adds a `List::drain_filter` iterator that moves items out of the list if they match a predicate. This is based on the [`drain_filter`] iterator on the `std::collections::LinkedList` type, but modified slightly. [`drain_filter`]: https://doc.rust-lang.org/stable/std/collections/struct.LinkedList.html#method.drain_filter
