* Fixes#4855 - Occasional h2spec failures on CI
In case of bad usage of the HTTP/2 API, we don't want to close()
the stream but just fail the callback, because the stream
may be performing actions triggered by a legit API usage.
In case of a call to `AsyncListener.onError()`, applications may decide to call
AsyncContext.complete() and that would be a correct usage of the Servlet API.
This case was not well handled and was wrongly producing a WARN log with an
`IllegalStateException`.
Completely rewritten `HttpTransportOverHTTP2.TransportCallback`.
The rewrite handles correctly asynchronous failures that now are executed
sequentially (and not concurrently) with writes.
If a write is in progress, the failure will just change the state and at the
end of the write a check on the state will determine what actions to take.
A session failure is now handled in HTTP2Session by first failing all the
streams - which notifies the Stream.Listeners - and then failing the session
- which notifies the Session.Listener.
The stream failures are executed concurrently by dispatching each one to a
different thread; this means that the stream failure callbacks are executed
concurrently (likely sending RST_STREAM frames).
The session failure callback is completed only when all the stream failure
callbacks have completed, to ensure that a GOAWAY frame is processed after
all the RST_STREAM frames.

Updates after review.
Now the Content-Length header is generated by HpackEncoder based on
MetaData.contentLength, so that the MetaData.HttpFields are not modified.

Introduced RateControl.Factory to create instances of RateControl
for each connection.
Modified relevant XML files and added distribution test for h2.

Reduce the number of RateControl fields, instead using common field in
HeaderParser.
Avoid null checking rateControl by having a NO_RATE_CONTROL static
HPack does not emit field with empty header name.
Apply rate control to any header parsing issue resulting in
session/stream failure

Implemented rate control for HTTP/2 frames using a single RateControl
object to avoid that each individual vulnerability is within limits,
but combined they still overload the server.
