We used std::ptr::eq elsewhere, but it should be the same.

Brings back `read_buf` from 0.2. This will be stabilized as part of 1.0.

If this means that bytes v1 will be released before tokio v1, I have no objection to adding these APIs. |

@taiki-e we are aiming to release bytes 1.0 w/ tokio 1.0. I would suggest watching the changes on that repo to track the direction. |
