[PATCH] updated resolve function/const conflict between namespace/class

Hi, The attached updated patch (which is also available at http://pear.php.net/~greg/resolvensfuncconst.patch.txt) adds support for call_user_func() resolution of the new function::blah format, as in: call_user_func('function::blah'); and adds a missing ns_071.inc file in the Zend/tests directory. Otherwise, it is identical to the previous patch in my message from yesterday. With the three patches I have posted for namespaces, all critical issues are resolved, leaving the sugar questions of namespace {} versus namespace; and other minor points raised by Liz Smith in her recent blog post on the subject.
