> MessageSerializer accepts buffer from ByteBufferStream, and invokes setBuffer for every message. But it looks like every MessageWriter use the same buffer every time, and this buffer is stored in GridIoSelectorNioSessionImpl#writeBuffer.
> We want to simplify API for MessageSerializer - remove buffer from readFrom, writeTo. Buffer is an implementation specific detail.
> Root changes:
>  # Remove ByteBuffer from MessageSerializer#writeTo, #readFrom
>  # Move setBuffer logic to DirectMessageReader/Writer
>  # Refactor ClientMessage handling in GridNioServer
