RequestLog can now be set on the HttpChannel and is called during the onCommitted callback.
The RequestLog may be set either on the server or via an updated RequestLogHandler that can
be applied to a specific context.
The HttpContent class has been reworked to store HttpField instances, we may be generated on
demand or instances of PreEncodedHttpField.
The encoding of HTTP2 fields has been generalized to handle both indexed and literal fields, selected
by header enum set.
Default servlet and response classes have been cleaned up in how they set response headers.
Introduced parameter "dispatchIO" in the relevant factories so that
they can be configured by users and connections will be created
taking into account this parameter.
For less configurable connection factories, this parameter is
currently hardcoded to either true or false depending on the case.
For example, ALPN and NPN connections have it to false, since they
don't do any blocking operation in onFillable().
Introduced ResetException, and using it when failing frames of streams
that have been reset already.
HttpTransportOverHTTP2.abort(Throwable) checks for this exception and
does not close the connection.
A PushCacheFilter contains the logic to associate secondary resources
to primary resources.
PushCacheFilter calls a Jetty-specific API on the request dispatcher:
Dispatcher.push(ServletRequest). This is a technology preview of the
push functionality slated for Servlet 4.0.
The push() invocation arrives to the transport and it is converted to
HTTP/2 specific PUSH_PROMISE, along with the mechanism to simulate
the request for the secondary resource.
No more need to copy protonego-alpn.xml to a jetty.base to specify
which protocols are advertised and in which order.
Instead, simply specify:
alpn.protocols=h2-14,http/1.1
alpn.defaultProtocol=http/1.1
in start.ini (in the example above for http2).

This refactor strives to remove duplication between the Metadata class and the HttpURI class.
Both classes have been made mutable (as they partially were anyway so best not to pretend).
HttpURI now holds the decomposed strings rather than a single string with indexes. This allows it to be rebuilt after changing just parts of the URI. It is now a lot more similar to the
JVM URI class and we could consider replacing it (after checking peformance).
Next step is to refactor the Request class to prevent it duplicating these fields.
