Fixes#4967 - Possible buffer corruption in HTTP/2 session failures
Partially reverted the changes introduced in #4855, because they
were working only when sends were synchronous.
Introduced ByteBufferPool.remove(ByteBuffer) to fix the issue.
Now when a concurrent failure happens while frames are being
generated or sent, the buffer is discarded instead of being
recycled, therefore resolving the buffer corruption.

Fixes#4976 HttpClient async content throws NPE in DEBUG log.
Reworked handling of asynchronous content by immediately exiting
HttpReceiverOverHTTP.process(), so that there is no race with
other threads that have been scheduled to resume the processing.
The call to HttpReceiver.dispose() that could be triggered by
an asynchronous failure is now performed either by the failing
thread (if the HttpReceiver is not processing) or by an I/O
thread (if the HttpReceiver is processing) similarly to what
happens when terminating the response.
The content decoding has been reworked to perform the required
state changes similarly to what non-decoded content is doing,
as this was completely lacking before (it was actually a side
bug that is now fixed).

* Issue #4965 - WINDOW_UPDATE for locally failed stream should not close the HTTP/2 session.
Improved HTTP2Session.onWindowUpdate() code to correctly check whether
the stream is already closed, and if so, just drop the WINDOW_UPDATE.
Refactored onResetForUnknownStream() to base class.
Other small refactorings to improve logging.

* 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.

* Issue #4936 large response header buffer corruption
If the response buffer is too large, the header buffer was released
but not nulled, then an exception thrown, which again released the
not nulled buffer. The buffer thus ends up in the buffer pool twice!
