 *  Breaking: Change `RecordedRequest.body` from a mutable `Buffer` to an immutable `ByteString`.

 *  Breaking: Adopt Okio's new `Socket` interface for `MockResponse.socketHandler`.

Note that any _Breaking_ changes above impact only APIs introduced in earlier 5.0.0-alpha releasees.
We don't break binary compatibility with non-alpha APIs.
