* Moved actors messages support from actix crate, enabled with feature `actors`.
* Breaking change: trait MessageBody requires Unpin and accepting Pin<&mut Self> instead of &mut self in the poll_next().
* MessageBody is not implemented for &'static [u8] anymore.
### Fixed
* Allow `SameSite=None` cookies to be sent in a response.
