* 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.

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 #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.

Now waking up the flusher via iterate() after a reset has been received.
This ensures that frames that may have stalled are removed from the
flusher queue.

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.
