uopz breaks user-level session storage

[donicek]

Call to php_uopz_clean_user_function and php_uopz_clean_user_class in PHP_RSHUTDOWN_FUNCTION (uopz.c:690-691) removes all user-defined functions, including user-defined session storage handlers which may still be needed later in RSHUTDOWN for PHP's session module in order to write session data and close the session properly.

This results in bogus PHP Warning: "Unknown: Failed to write session data (user). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0" and breaks user-level session storage when uopz module is enabled.

This is not a problem any longer with v5.
