Brad Fitzpatrick cad4e97af8 [release-branch.go1.7] net/http, net/http/cgi: fix for CGI + HTTP_PROXY security issue
Because,

* The CGI spec defines that incoming request header "Foo: Bar" maps to
  environment variable HTTP_FOO == "Bar". (see RFC 3875 4.1.18)

* The HTTP_PROXY environment variable is conventionally used to configure
  the HTTP proxy for HTTP clients (and is respected by default for
  Go's net/http.Client and Transport)

That means Go programs running in a CGI environment (as a child
process under a CGI host) are vulnerable to an incoming request
containing "Proxy: attacker.com:1234", setting HTTP_PROXY, and
changing where Go by default proxies all outbound HTTP requests.

This is CVE-2016-5386, aka https://httpoxy.org/

Fixes #16405
