* Issue #2439 - Remove HTTP/2 data copy.
Implemented reference counting for the network buffer, with the
semantic that calling succeeded() on callbacks decrements the
reference count.
Introduced interface Retainable, used by the client when notifying
multiple application content listeners.

Fixed by start reading from the server after the session
promise has been notified, which may send the first request.

Updated the logic to avoid sending an empty data frame
when only sending the trailers in HttpTransportOverHTTP2.send().

* Fixes#2366 - Review HTTP/2 interleaving.
Now using a fairer algorithm that performs multiple generation passes
but without generating all frames for the current entries - it stops
after N passes over all the entries when the number of bytes to
write is large enough.
Using HttpConfiguration.outputBufferSize as the writeThreshold on
the server and a default 32 KiB on the client to stop the generation
after a pass over all the entries.

Removed usage of ternary expressions in favor of if/else statements
to improve readability of the logic for the send() method.

The problem was caused by the reset arriving to the server
_before_ the commit callback was invoked.
Now waiting for the commit callback to complete before
sending the reset to the server.

* 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.

Now exiting the parse loop when the response is complete; if there
are bytes remaining in the buffer, then it's cleared out.

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

Also introduced HTTP2Client.bindAddress, again forwarded from HttpClient.

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.
* Implementation of #1803 proposal 2 - EITHER dispatch type for EWYK
