http2: delay sending request body in Transport if 100-continue is set
In Go 1.6, the HTTP/1 client got Transport.ExpectContinueTimeout.
This makes the HTTP/2 client respect a Request's "Expect:
100-continue" field and the Transport.ExpectContinueTimeout
configuration.
This also makes sure to call the traceWroteRequest hook if the server
replied while we're still writing the request, since that code was
in the same spot and it couldn't be trivially separated.
