*  Breaking: Decompose the `RecordedRequest.requestLine` into three properties, `method`, `target`,
    and `version`. This better suits HTTP/2 where the request line had to be synthesized from
    component headers.

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

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

If <code>n</code> &lt= 0, the loop does not run any iterations.

<li>
For a function <code>f</code>, the iteration proceeds by calling <code>f</code>
with a new, synthesized <code>yield</code> function as its argument.
If <code>yield</code> is called before <code>f</code> returns,
the arguments to <code>yield</code> become the iteration values
for executing the loop body once.
