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.

Fixed test failure after merge.
Made sure the lastStreamId is updated when resetting a new
stream since it has been seen by the server and handled.
This avoids that a new stream arriving during shutdown is
interpreted as a connection failure, therefore failing all
pending streams - we want them to complete.

Fixes#4971 - Simplify Connection.upgradeFrom()/upgradeTo().
Now the upgrade-from connection produces a "floating" buffer
(not belonging to a pool), so that it can release the original buffer.
The upgrade-to connection is free to copy or store this "floating" buffer.
Strengthened ByteBufferPool behavior when releasing non-pooled
ByteBuffers: the buffer is now discarded.
Updated javadocs and all implementations.

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.

* 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.

* 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.

Introduced:
* Request Request.headers(Consumer<HttpFields.Mutable>).
This allows applications to modify the headers, and chain calls.
It also delegates the precise semantic of put/add/remove/clear to HttpFields, so there is no API duplication.
* HttpRequest.header(HttpField) to efficiently add fields while normalizing the request (only used in implementation).
* HttpResponse.header(HttpField) to efficiently add fields while parsing the response (only used in implementation).
This pairs with HttpResponse.trailer(HttpField).
* HttpResponse.headers(Consumer<HttpFields.Mutable>) to modify the fields after they have been populated (only used in tests).
Removed:
* Request.[set,add,put,remove], replaced by headers(Consumer<HttpFields.Mutable>).
Deprecated:
* Request.header(String, String)
* Request.header(HttpHeader, String)
Both replaced by headers(Consumer<HttpFields.Mutable>) with clearer semantic for add/put/remove.
All the rest is code cleanup to remove the usage of the deprecated header() methods.
