Fix segfault in wrapper error log mechanism when errors are logged on

second and subsequent events.
Implement very simple recursion protection for user streams written
like this:
class urlEncodeStream {
    var $fp = NULL;

    function stream_open($path, $mode, $options, &$opened_path)
    {
        $this->fp = fopen($path, $mode); // <-- this recurses infinitely
        return is_resource($this->fp);
    }
}

file_register_wrapper('urlencode', 'urlEncodeStream');
$fp = fopen('urlencode:///tmp/outputfile.txt', 'w');
