Apparently this causes Solaris 10 servers to refuse our NFSv4 SETCLIENTID
calls. Fall back to root creds for now, since most servers that care are
very likely to have root squashing enabled.

We need to try to ensure that we always use the same credentials whenever
we re-establish the clientid on the server. If not, the server won't
recognise that we're the same client, and so may not allow us to recover
state.

With the recent change to generic creds, we can no longer use
cred->cr_ops->cr_name to distinguish between RPCSEC_GSS principals and
AUTH_SYS/AUTH_NULL identities. Replace it with the rpc_authops->au_name
instead...

We need the ability to treat 'generic' creds specially, since they want to
bind instances of the auth cred instead of binding themselves.

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.
