NeilBrown 1de7eea929 SUNRPC: add side channel to use non-generic cred for rpc call. ... The credential passed in rpc_message.rpc_cred is always a generic credential except in one instance. When gss_destroying_context() calls rpc_call_null(), it passes a specific credential that it needs to destroy. In this case the RPC acts *on* the credential rather than being authorized by it. This special case deserves explicit support and providing that will mean that rpc_message.rpc_cred is *always* generic, allowing some optimizations. So add "tk_op_cred" to rpc_task and "rpc_op_cred" to the setup data. Use this to pass the cred down from rpc_call_null(), and have rpcauth_bindcred() notice it and bind it in place.
