NFS: add COPY_NOTIFY operation
Try using the delegation stateid, then the open stateid. Only NL4_NETATTR, No support for NL4_NAME and NL4_URL. Allow only one source server address to be returned for now. To distinguish between same server copy offload ("intra") and a copy between different server ("inter"), do a check of server owner identity and also make sure server is capable of doing a copy offload.
