Incompatible Change

For implementing new protocols more nature, XProtocol is no longer as a protocol and no subprotocol any more.
XProtocol is a framework to implement protocol easier now.
So, the old existing code for implementing new protocols need some changes,
please see this doc(In Chinese) for changing the old existing code suit for the new release.
