Now CONNECT with :protocol requests will demand DATA frames only
after the upgrade.
Other requests will demand DATA frames during the handling of
the request HEADERS frame.

for each connection.
Modified relevant XML files and added distribution test for h2.

Invalid HTTP/2 headers are now causing an error rather than being ignored.
HTTP2Flusher now catches HpackException.StreamException and generates a
RST_STREAM frame, rather than just closing the connection.
Modified HpackEncoder to throw HpackException in case of encoding failure.
Introduced HpackEncoder.validateEncoding (defaults true) so validation of
the headers can be disabled (useful for tests).

Made sure that Stream.Listener.onBeforeData() returns before calling
Stream.Listener.onData().
Added test cases also for calling demand() outside data events.

Introduced a Response.DemandedContentListener to explicitly separate
the will to request more content from the notification that the content
has been consumed.
Updated all transports to follow the new semantic: rather than waiting
for the callback to complete before delivering more content, now they
wait for the demand to be positive to deliver more content.
Since now the content may be unconsumed but there can be more demand,
all transport implementation had to be changed to use RetainableByteBuffer
to retain content buffers that were not consumed.

Code cleanups and reformatting.
Fixed logic for SETTINGS frame replies: they are not subject to rate control.

Renamed onDataRequested() to onDataDemanded() to
avoid using the "request" word which is overloaded.

Reduce the number of RateControl fields, instead using common field in
HeaderParser.
Avoid null checking rateControl by having a NO_RATE_CONTROL static
HPack does not emit field with empty header name.
Apply rate control to any header parsing issue resulting in
session/stream failure

Fixed race in WindowRateControl by only removing the event that we
just inspected.
Added an AtomicInteger to track the size to avoid iterating over the
linked list.

Implemented rate control for HTTP/2 frames using a single RateControl
object to avoid that each individual vulnerability is within limits,
but combined they still overload the server.
