Go's http1 implementation originally had a mechanism to send HTTP
trailers based on pre-declaring the trailer keys whose values you'd
later let after the header was written.
http2 copied the same mechanism, but it was found to be unsufficient
for gRPC's wire protocol. A second trailer mechanism was added later
(but only to http2) for handlers that want to send a trailer without
knowing in advance they'd need to.
Copy the same mechanism back to http1 and document it.

Using Result() to convert Recorder into a http.Response yields a much
better user experience.

In Go versions 1 up to and including Go 1.6,
ResponseRecorder.HeaderMap was both the map that handlers got access
to, and was the map tests checked their results against. That did not
mimic the behavior of the real HTTP server (Issue #8857), so HeaderMap
was changed to be a snapshot at the first write in
https://golang.org/cl/20047. But that broke cases where the Handler
never did a write (#15560), so revert the behavior.
Instead, introduce the ResponseWriter.Result method, returning an
*http.Response. It subsumes ResponseWriter.Trailers which was added
for Go 1.7 in CL 20047. Result().Header now contains the correct
answer, and HeaderMap is unchanged in behavior from previous Go
releases, so we don't break people's tests. People wanting the correct
behavior can use ResponseWriter.Result.

Trailers() returns the headers that were set by the handler after the
headers were written "to the wire" (in this case HeaderMap) and that
were also specified in a proper header called "Trailer".
Neither HeaderMap or trailerMap (used for Trailers()) are manipulated by
the handler code, instead a third stagingMap is given to the
handler. This avoid a reference kept by handler to affect the recorded
results.
If a handler just modify the header but doesn't call any Write or Flush
method from ResponseWriter (or Flusher) interface, HeaderMap will not be
updated. In this case, calling Flush in the recorder is enough to get
the HeaderMap filled.
