speed up http considerably via fix for io.Discard #2084
Description
When the http body is closed, io.Copy(ioutil.Discard, ...) needlessly allocates a new buffer every time. This seems pretty minor but the effect is considerable. My most recent tests bump from 3000qps -> 3800qps after this change. Since this is just discard, I don't *think* there a race stomping the underlying data since each call to read is using a distinct slice.
