Rollup merge of #22990 - japaric:privATe, r=alexcrichton

 Associated types are now treated as part of the public API by the privacy checker.

If you were exposing a private type in your public API via an associated type, make that type public:

``` diff
  pub struct PublicType { .. }

- struct Struct { .. }
+ pub struct Struct { .. }

  pub trait PublicTrait {
      type Output;

      fn foo(&self) -> Self::Output;
  }

  impl PublicTrait for PublicType {
      type Output = Struct;

      fn foo(&self) -> Struct {  // `Struct` is part of the public API, it must be marked as `pub`lic
          ..
      }
  }
```
