Description:
------------
PHP $_SERVER['HTTP_*'] superglobal and getallheaders() does not actually give all headers.
If you have multiple header lines with same name, each SAPI does totally different thing(and all of
them are wrong)

If I make request:
GET / HTTP/1.1
Forwarded: for=10.0.0.1,for=20.30.40.50;host=php.net,host=awesome.proxy.com;proto=https,proto=http
Forwarded: for=10.30.20.10;host=second.awesome.proxy.com;proto=http

I get 3 different responses based on SAPI

FPM only keeps last header
php -s only keeps first header
apache concatenates them with ,

PHP should implement new method to get all headers OR implement some class that has method to get
all headers
