fixing opcode modification in namespace implementation

Hi, I assigned this to helly arbitrarily, but wanted to make sure that Stas and Dmitry also see it. This should be fixed ASAP. The opcode modification was easy to fix, since we weren't using op1. I also fixed a cosmetic issue Dmitry wanted fixed, which was replacing the non-verbose 1 and 2 used to identify namespace constant vs. namespace function in zend_resolve_non_class_name() with #defines. http://bugs.php.net/bug.php?id=46500 patch at http://pear.php.net/~greg/fix_ns1.patch.txt Greg
