listen proxy_protocol and rewrite redirect scheme

[adrhc]

Hi, I'm sorry but I mistakenly claimed to work the patch:

#if (NGX_HTTP_SSL) 
if (c->ssl || port == 443) { 
*b->last++ ='s'; 
} 
#endif 

In order to work nginx needs this config:
	server {
		listen 127.0.0.1:443		proxy_protocol;
		port_in_redirect			on;

and stunnel:
[tls to http]
sni = tls:*
connect = 127.0.0.1:443
protocol = proxy
