http2: add support for graceful shutdown of Server
This adds support for gracefully shutting down the Server, including
sending a GOAWAY frame to clients and shutting down when things are
idle. For now this support is only when integrated with the standard
library's Server.
A future change could export some of this.
Updates golang/go#4674
