Add Result::cloned{,_err} and Result::copied{,_err}
This is a little nice addition to `Result`.
1. I'm not sure how useful are `cloned_err` and `copied_err`, but for the sake of completeness they are here.
2. Naming is similar to `map`/`map_err`. I thought about naming `cloned` as `cloned_ok` and add another method called `cloned` that clones both Ok and Err, but `cloned_ok` should be more prevalent than `cloned_both`.

core: Stabilize FusedIterator
...
FusedIterator is a marker trait that promises that the implementing
iterator continues to return `None` from `.next()` once it has returned
`None` once (and/or `.next_back()`, if implemented).
The effects of FusedIterator are already widely available through
`.fuse()`, but with stable `FusedIterator`, stable Rust users can
implement this trait for their iterators when appropriate.
