This code ensures X-Forward (and friends) headers are updated correctly when using stacked proxies: the host, protocol and "for" should be inherited from the previous proxies.

Of course, there are 3 competing/similar ways to retrieve this information from the previous Proxy, so this tries to be compatible with them all:

• Forwarded (new, nicer and standardized in rfc7239)
• X-Forwarded-[For/Host/Proto], the legacy but de-facto standard
• X-Real-IP, a less-common alternative to X-Forwarded-For[0].

Also, retrieving them from the incoming request requires caution: Malicious clients may try inject these headers, so these headers should only be used when we expect them.
