     Convert the Kerberos 5 credential to Kerberos 4 credential.  This is done
     by sending them to the 524 service in the KDC.

     kkrrbb552244__ccoonnvveerrtt__ccrreeddss__kkddcc() converts the Kerberos 5 credential in _i_n___c_r_e_d
     to Kerberos 4 credential that is stored in _c_r_e_d_e_n_t_i_a_l_s.

     kkrrbb552244__ccoonnvveerrtt__ccrreeddss__kkddcc__ccccaacchhee() is different from
     kkrrbb552244__ccoonnvveerrtt__ccrreeddss__kkddcc() in that way that if _i_n___c_r_e_d doesn't contain a
     DES session key, then a new one is fetched from the KDC and stored in the
     cred cache _c_c_a_c_h_e, and then the KDC is queried to convert the credential.

     This interfaces are used to make the migration to Kerberos 5 from Ker-
     beros 4 easier.  There are few services that still need Kerberos 4, and
     this is mainly for compatibility for those services.  Some services, like
     AFS, really have Kerberos 5 supports, but still uses the 524 interface to
     make the migration easier.
