* Moved implementation of UpgradeTo from HTTP2ServerConnection
to HTTP2Connection, since now also the client connection
can be upgraded to.
* Split HTTP2Session.newStream(), since now the client must
be able to create the implicit stream 1 corresponding to
the HTTP/1.1 upgrade request, so that the HTTP/2 response
after the upgrade finds the stream.
* The HTTP/1.1 upgrade mechanism has been generalized.
Before it was based on HttpConnectionUpgrader and a hook
in HttpChannelOverHTTP.exchangeTerminating().
Now it is based on UpgradeProtocolHandler that when sees
a 101 response it will trigger the upgrade mechanism.
* Introduced ConnectionPool.accept(Connection) to transfer
a connection from the HTTP/1.1 connection pool to the
HTTP/2 connection pool after the upgrade.

the request HEADERS frame.

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.
