Fix for bug 19207 (change of cgi behaviour in PHP 4.3.0)

Attached is a patch that fixes bug #19207 in accordance with previous discussion on php-dev. It add cgi.rfc2616_headers ini option which is by default set to off and mimics current 4.3.0 behaviour. If its set to on the HTTP status line is sent in accordance to RFC2616 which was default for PHP 4.2.3 and earlier. Any objections to commiting this fix? Edin
