- Move common methods from ByteBuf to Buf - Rename ensureWritableBytes() to ensureWritable() - Rename readable() to isReadable() - Rename writable() to isWritable() - Add isReadable(int) and isWritable(int) - Add AbstractMessageBuf - Rewrite DefaultMessageBuf and QueueBackedMessageBuf - based on Josh Bloch's public domain ArrayDeque impl
