Motivation: The Http2DefaultFrameWriter copies all contents into a buffer (or uses a CompositeBuffer in 1 case) and then writes that buffer to the socket. There is an opportunity to avoid the copy operations and write directly to the socket. Modifications: - Http2DefaultFrameWriter should avoid copy operations where possible. - The Http2FrameWriter interface should be clarified to indicate that ByteBuf objects will be released. Result: Hopefully less allocation/copy leads to memory and throughput performance benefit.
