Fixed MaxConcurrentStreamsTest - it was always broken.
The problem was that the call to super.onSettings(...) was done
_after_ sending the request, so the connection pool was still
configured with the default maxMultiplex=1024.
Also fixed AbstractConnectionPool to avoid a second call to
activate() if we are not trying to create a new connection.

* 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.

* Fixes#4904 - WebsocketClient creates more connections than needed.
Fixed connection pool's `acquire()` methods to correctly take into account the number of queued requests.
Now the connection creation is conditional, triggered by
explicit send() or failures.
The connection creation is not triggered _after_ a send(),
where we aggressively send more queued requests - or
in release(), where we send queued request after a previous
one was completed.
Now the connection close/removal aggressively sends more
requests triggering the connection creation.
Also fixed a collateral bug in `BufferingResponseListener` - wrong calculation of the max content length.
Restored `ConnectionPoolTest` that was disabled in #2540, cleaned it up, and let it run for hours without failures.

Modified jetty-alpn-openjdk8-* classes to support both
pre 8u252 (via alpn-boot) and post 8u252 (via standard API).
Replaced usages of -Xbootclasspath with -javaagent, and
using Jetty ALPN Agent jar rather than Jetty ALPN boot jar.
Removed all alpn-1.8.0*.mod files since now it is
possible to use a fixed version of the ALPN Agent
to cover all the versions.

* Issue #4265 Remove doError
The doError method and the ErrorDispatchHandler class were
hang overs from when we needed to dispatch into a context to get sendError called, which would then generate the error page.
Now sendError doesn't do any generation, rather it changes state that arranges either for a minimal error page to be generated or an ERROR dispatch to a real handler/servlet to generate the error page.
Thus the ErrorDispatchHandler and doError methods can now be removed.

Invalid HTTP/2 headers are now causing an error rather than being ignored.
HTTP2Flusher now catches HpackException.StreamException and generates a
RST_STREAM frame, rather than just closing the connection.
Modified HpackEncoder to throw HpackException in case of encoding failure.
Introduced HpackEncoder.validateEncoding (defaults true) so validation of
the headers can be disabled (useful for tests).

Introduced a Response.DemandedContentListener to explicitly separate
the will to request more content from the notification that the content
has been consumed.
Updated all transports to follow the new semantic: rather than waiting
for the callback to complete before delivering more content, now they
wait for the demand to be positive to deliver more content.
Since now the content may be unconsumed but there can be more demand,
all transport implementation had to be changed to use RetainableByteBuffer
to retain content buffers that were not consumed.

Code cleanups and reformatting.
Fixed logic for SETTINGS frame replies: they are not subject to rate control.
Signed-off-by: Simone Bordet <simone.bordet@gmail.com>
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
