Can you add a test case that fails before your change and succeeds after? |

Make it a bit simpler and make it reusable.
This test is supposed to check for stream unchunking, but it's not really effective with that because chunks created by createChunkedBody() get wrapped into another chunk by writeBodyStream(), so we end up with chunkedBody in request handler although what we really want is plain body. Deduplicate test and benchmark also.
It wasn't actually compatible with io.Reader as io.Reader _never_ returns n >
len(p) while this function easily did that for chunked payloads confusing its
users:

It also returned len(p) in some cases where it read less than that.

io.Readerinterface provided byrequestStreamis broken for chunks exceedinglen(p)which can lead to various panics in code usingRead().
