> The XDR class is one fundamental aspect in the current implementation of NFS server.
While the client might potentially have a higher level APIs, it also requires redundant copying
since the upstream clients have insufficient information.
> This JIRA introduces a new class, RpcInfo, which (1) decouples XDR from the APIs, turning
it into a utility class, and (2) exposes ChannelBuffer directly to the client in order to
open the opportunity for avoid copying.
