[quicwg/base-drafts] What indicates the end of a message? (#2230)

When a stream is closed, this indicates the end of an HTTP message. Because some
messages are large or unbounded, endpoints SHOULD begin processing partial HTTP
messages once enough of the message has been received to make progress.  If a
client stream terminates without enough of the HTTP message to provide a
complete response, the server SHOULD abort its response with the error code
HTTP_INCOMPLETE_REQUEST.

This creates two ways to say the end of the HTTP messages:

- Send the HEADERs frame (at which point you have to close,
  but you know its done)
- Don't send the HEADERs frame and close the stream

That seems a bit unfortunate. Would it make more sense to require the final HEADERS frame, even if it were empty?

Also, can the server send PUSH_PROMISE after the second HEADERS. I think no, but...
