* Extending the krb5_get_init_creds_opt structure. The original
* krb5_get_init_creds_opt structure is defined publicly. The

* assumed a pre-allocated structure which was passed to
* krb5_get_init_creds_init(). The new interface assumes that
* the caller will call krb5_get_init_creds_alloc() and
* krb5_get_init_creds_free().
*
* Callers MUST NOT call krb5_get_init_creds_init() after allocating an
* opts structure using krb5_get_init_creds_alloc(). To do so will
* introduce memory leaks. Unfortunately, there is no way to enforce
* this behavior.
*
* Two private flags are added for backward compatibility.
* KRB5_GET_INIT_CREDS_OPT_EXTENDED says that the structure was allocated
* with the new krb5_get_init_creds_opt_alloc() function.
* KRB5_GET_INIT_CREDS_OPT_SHADOWED is set to indicate that the extended
* structure is a shadow copy of an original krb5_get_init_creds_opt
* structure.
* If KRB5_GET_INIT_CREDS_OPT_SHADOWED is set after a call to
* krb5int_gic_opt_to_opte(), the resulting extended structure should be
* freed (using krb5_get_init_creds_free). Otherwise, the original
* structure was already extended and there is no need to free it.
