e440065a0f [iter_overeager_cloned]: detect .cloned().map() and .cloned().for_each()
key idea:
for `f` in `.map(f)` and `.for_each(f)`:
1. `f` must be a closure with one parameter
2. don't lint if mutable paramter in clsure `f`: `|mut x| ...`
3. don't lint if parameter is moved

fc061890d6 [iter_overeager_cloned]: detect .cloned().filter() and .cloned().find()
Key idea:
```
// before
iter.cloned().filter(|x| unimplemented!() )
// after
iter.filter(|&x| unimplemented!() ).cloned()

// before
iter.cloned().filter( foo )
// after
iter.filter(|&x| foo(x) ).cloned()
```
