Motivations: The HPACK code was not really optimized and written with Netty types in mind. Because of this a lot of garbage was created due heavy object creation. This was first reported in [#3597] and https://github.com/grpc/grpc-java/issues/1872 . Modifications: - Directly use ByteBuf as input and output - Make use of ByteProcessor where possible - Use AsciiString as this is the only thing we need for our http2 usage Result: Less garbage and better usage of Netty apis.
