Make EOF and errors be special content.
Transition to a much simplified FSM by using the needContent() / produceContent() model.
Implement blocking on top of async, this way there is only one FSM.

* Fixes#3766 - Introduce HTTP/2 API to batch frames.
Introduced Stream.FrameList to hold HEADERS+DATA+HEADERS frames.
These are often used by the client and by the server when the
request/response content is known and FrameList will allow to
send them in a single TCP write, rather than multiple ones.
Rewritten HttpSenderOverHTTP2.sendHeaders() and
HttpTransportOverHTTP2.sendHeaders() to take advantage of
FrameList.
Now using ConcurrentHashMap as a client context, because
with DEBUG logging enabled it may be access concurrently.

* Replaced relevant usages of synchronized with AutoLock.
* Made AutoLock serializable since classes that use it may be stored in the HttpSession.
* Added convenience methods to AutoLock to execute lambdas with the lock held.
* Introduced AutoLock.WithCondition to use a Lock and a Condition together.

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.

- ArrayList contains() + add() is faster than HashSet add() for small collections
- A heap allocation of the iterator is required when iterating HashSet while iterating ArrayList can do with a stack allocation

* Moved implementation of UpgradeTo from HTTP2ServerConnection
to HTTP2Connection, since now also the client connection
can be upgraded to.
* Split HTTP2Session.newStream(), since now the client must
be able to create the implicit stream 1 corresponding to
the HTTP/1.1 upgrade request, so that the HTTP/2 response
after the upgrade finds the stream.
* The HTTP/1.1 upgrade mechanism has been generalized.
Before it was based on HttpConnectionUpgrader and a hook
in HttpChannelOverHTTP.exchangeTerminating().
Now it is based on UpgradeProtocolHandler that when sees
a 101 response it will trigger the upgrade mechanism.
* Introduced ConnectionPool.accept(Connection) to transfer
a connection from the HTTP/1.1 connection pool to the
HTTP/2 connection pool after the upgrade.
