- Use memset instead of ZeroMemory, just to be consistent with Ove's

code.
- Add some assertions where assumptions are made (need way more).
- Plug the binding handle into the RPC_MESSAGE during NdrGetBuffer.
- Implement NdrSendReceive.
- Attempt to support client and server bindings in I_RpcSend[Receive].
