SUNRPC: Fix RPCAUTH_LOOKUP_ROOTCREDS
The current RPCAUTH_LOOKUP_ROOTCREDS flag only works for AUTH_SYS authentication, and then only as a special case in the code. This patch removes the auth_sys special casing, and replaces it with generic code.

SUNRPC: Add a generic RPC credential
Add an rpc credential that is not tied to any particular auth mechanism, but that can be cached by NFS, and later used to look up a cred for whichever auth mechanism that turns out to be valid when the RPC call is being made.

SUNRPC: Add an rpc_credop callback for binding a credential to an rpc_task
We need the ability to treat 'generic' creds specially, since they want to bind instances of the auth cred instead of binding themselves.

SUNRPC: Add a helper rpcauth_lookup_generic_cred()
The NFSv4 protocol allows clients to negotiate security protocols on the fly in the case where an administrator on the server changes the export settings and/or in the case where we may have a filesystem migration event.
Instead of having the NFS client code cache credentials that are tied to a particular AUTH method it is therefore preferable to have a generic credential that can be converted into whatever AUTH is in use by the RPC client when the read/write/sillyrename/... is put on the wire.
We do this by means of the new "generic" credential, which basically just caches the minimal information that is needed to look up an RPCSEC_GSS, AUTH_SYS, or AUTH_NULL credential.
