* Issue #2349 - Review HTTP/2 max streams enforcement.
Changed the max concurrent remote streams enforcement algorithm.
It is now based on the stream count and the closing stream count,
updated atomically in a state machine in HTTP2Stream.
Fixed Javadoc.
Fixed close() method.

Dumping also HttpChannelOverHTTP2 when dumping the HTTP2Stream.
The channel is now stored as a field in HTTP2Stream rather than
as an attribute to save the attributes map allocation.
Consequently, IStream has now getter/setter for the property
"attachment" that is used to store the channel without having
a type dependency on HttpChannel.

Introduced property connectBlocking in HTTP2Client so that it can
be forwarded by HttpClient and then used for HTTP/2 connects.
Also introduced HTTP2Client.bindAddress, again forwarded from HttpClient.

Issue #2293 Pending Multiplexed Connections
Added a AtomicBiInteger to allow both total connections and pending connections to be encoded in the
same atomic int.

Merging this PR for #2199 as we currently think it is not worse than previous and the code base is definitely simpler. While JMH has shown significant benefits for this approach, we have yet been able to demonstrate them in full scale integration tests - however that is likely due to GC and thread pool issues dominating.
A `org.eclipse.jetty.http2.PEC_MODE` System property has been added to allow the EWYK scheduling to be disabled for HTTP/2 if need be.

Issue #2081 No idle timeout exception when dispatch is delayed
* Delegate the readtimeout handling to HttpChannel so that a delayed dispatch can be ended.
* Added unit test for delayed dispatch idle
* Now using HttpInput.onIdleTimeout() to fail the HttpInput, and then dispatching the request in case it has not been dispatched yet. This ensure consistent behavior independently of the value of HttpConfiguration.delayDispatchUntilContent.
* Fixed for both HTTP/1.1 and HTTP/2.
* Added tests for non-blocking reads.

* Issue #1973 - Implement minimum response data rate.
Implemented response content data rate control in HttpOutput.
Introduced a WriteFlusher.Listener interface that produces events
for every flush(). These events are forwarded to the Connection
and from there to the HttpOutput so that the data rate control can
be enforced.
Both HTTP/1.1 and HTTP/2 are implemented.
Data rate control for HTTP/1.1 is approximate because it will count
also headers bytes and the chunk bytes, while for HTTP/2 is precise.

Because now the failures are asynchronous, code that was executed after
invoking the failure listener must be now executed after the
asynchronous processing done by the listener and therefore Callbacks
are introduced.
Idle timeout have a special meaning in that they become a no-operation
if the application is dispatched but idle (neither reading nor writing).
HttpChannelOverHTTP2 now forwards the idle timeout to HttpInput, which
will only change its state if it is interested in reading.
HttpInput.consumeAll() has been modified to consume all input even if
it's already failed.
Failures caused by the other peer (e.g. I/O failures or stream resets)
are now retained and will eagerly consumed any queued data to free up
the flow control windows.
Introduced ConnectionPool.Factory and HttpClientTransport.connectionPoolFactory.
This allows applications to create a ConnectionPool given the HttpDestination.
Since requests cannot be connection delimited, don't call
sslEngine.closeInbound() on the server.
On the client, added a configuration parameter to allow missing
TLS Close Message, since many servers do that.
Introduced SslConnection.allowMissingCloseMessage so that it
throws in case of truncation attacks.
Implemented support in the generic HttpChannel and Request classes.
Linked HTTP/1.1 and HTTP/2 trailers to call HttpChannel, so that trailers
are now available in Servlet APIs by casting to Jetty's Request class.
The semantic is that trailers will only be available _after_ reading
the request content.
It's common for a client to either close the connection or reset a
stream, so EofException is a better exception to report since it will
be logged at DEBUG level by the server, reducing the noise in the logs.
* Updated Maven plugins to versions that support JDK 9.
* Added jdk9 profiles to the build files.
* Introduced modules jetty-alpn-java-client and jetty-alpn-java-server
containing a pure JDK 9 implementation of ALPN.
* Wired ALPN connection factories (client and server) to use the proper
ALPN implementation based on the JDK platform version (8 or 9).
The fix notifies the transport when a reset frame is received,
allowing the transport to fail the write callback which then notifies
the application, either by throwing (in case of blocking writes) or
by calling error listeners.
Also added a guard, in HttpChannel.handle() for the ERROR_DISPATCH case,
that checks if the response is already committed, and if so, abort
the transport - similar to what's already there for 9.4.
