Merge #109

109: Release 0.4.0 r=taiki-e a=taiki-e cc #21 ### Changes since the latest 0.3 release: * **Pin projection has become a safe operation.** In the absence of other unsafe code that you write, it is impossible to cause undefined behavior. (#18) * `#[unsafe_project]` attribute has been replaced with `#[pin_project]` attribute. (#18, #33) * The `Unpin` argument has been removed - an `Unpin` impl is now generated by default. (#18) * Drop impls must be specified with `#[pinned_drop]` instead of via a normal `Drop` impl. (#18, #33, #86) * `Unpin` impls must be specified with an impl of `UnsafeUnpin`, instead of implementing the normal `Unpin` trait. (#18) * `#[pin_project]` attribute now determines the visibility of the projection type/method is based on the original type. (#96) * `#[pin_project]` can now be used for public type with private field types. (#53) * `#[pin_project]` can now interoperate with `#[cfg()]`. (#77) * Added `project_ref` method to `#[pin_project]` types. (#93) * Added `#[project_ref]` attribute. (#93) * Removed "project_attr" feature and always enable `#[project]` attribute. (#94) * `#[project]` attribute can now be used for `impl` blocks. (#46) * `#[project]` attribute can now be used for `use` statements. (#85) * `#[project]` attribute now supports `match` expressions at the position of the initializer expression of `let` expressions. (#51) ### Changes since the 0.4.0-beta.1 release: * Fixed an issue that caused an error when using `#[pin_project(UnsafeUnpin)]` and not providing a manual `UnsafeUnpin` implementation on a type with no generics or lifetime.
