Moved the initialization of the SETTINGS frame to a common place
shared by both the low-level HTTP2Client and the higher level
HttpClientTransportOverHTTP2.
Did the same with HTTP2 server ConnectionFactories.

* 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.

* 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.

* 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.
* Implementation of #1803 proposal 2 - EITHER dispatch type for EWYK
* made code more readable
* increase small threadpools in tests for extra reserved thread
* clean up
* minor code simplifications
* Work in progress to simplify reserved thread pool
* use a single ReservedThreadPool built into the QueuedThreadPool
* fixed javadoc
* removed more old reserved thread references
* disable EWYK for h2
* fixes from review
* use EWYK for HTTP2
* Fixed javadocs, imports and QueuedThreadPool constructors.
* fix javadoc
* EWYK avoid unnecessary pendings
* after review
* fixed merge with jetty-threadpool.xml
* alternate EWYK implementations
* added jetty copyright headers
* Simplified EWYK code after review
* fixed bad merge
* Code cleanups.
* Improved Javadocs for deprecated property "reservedThreads".
* Improved Javadocs for deprecated property "reservedThreads".
* added a system property to enable only PEC for HTTP/2
