Kevin Coffman 47d8480776 gss_krb5: handle new context format from gssd
For encryption types other than DES, gssd sends down context information
in a new format.  This new format includes the information needed to
support the new Kerberos GSS-API tokens defined in rfc4121.

kernel.  This will allow us to change the format of the context
information sent down from gssd to include only a single key.
