SUNRPC: Define rpcsec_gss_info structure
The NFSv4 SECINFO procedure returns a list of security flavors. Any GSS flavor also has a GSS tuple containing an OID, a quality-of- protection value, and a service value, which specifies a particular GSS pseudoflavor. For simplicity and efficiency, I'd like to return each GSS tuple from the NFSv4 SECINFO XDR decoder and pass it straight into the RPC client. Define a data structure that is visible to both the NFS client and the RPC client. Take structure and field names from the relevant standards to avoid confusion.
