RAD — Number of security policies supporteb by PolicyEvaluator arbitrarily large

The number of security policies supported by a PolicyEvaluator could be
arbitrarily large. Because of this the operation "list_policies" in the
PolicyEvaluatorAdmin interface might be changed to:

PolicyNameIter list_policies(in num_ret, in max_iter, out
PolicyNameList policy_names);

where max_iter is maximum number of entries held by the iterator, num_ret
is the maximum number of entries returned in the "out PolicyNameList list"
argument, and "policy_names" is sequence of PolicyNames having at most
"num_ret" entries. If the list of policy names has less than "num_ret"
entries, the iterator will be nil.

The iterator interface would look like:

interface PolicyNameIter

;

Note this technique could be carried to the extreme for all those
operations that return a PolicyEvaluatorList. However, it seems less likely
that one would has assigned large numbers of evaluator in the same way one
might have large numbers of security policies.
