This commit is largely based on work by Thiago Arrais (@thiagoarrais)
and Shane Bradfield (@l33tLumberjack). I wasn't really able to get their
PR reasonably merged onto the latest master, so I reapplied their changes
manually here and did some further improvements on that.

-"""
-This inline scripts makes it possible to use mitmproxy in scenarios where IP spoofing has been used to redirect
-connections to mitmproxy. The way this works is that we rely on either the TLS Server Name Indication (SNI) or the
-Host header of the HTTP request.
-Of course, this is not foolproof - if an HTTPS connection comes without SNI, we don't
-know the actual target and cannot construct a certificate that looks valid.
-Similarly, if there's no Host header or a spoofed Host header, we're out of luck as well.
-Using transparent mode is the better option most of the time.
-
-Usage:
-    mitmproxy
-        -p 443
-        -s dns_spoofing.py
-        # Used as the target location if neither SNI nor host header are present.
-        -R http://example.com/
-    mitmdump
-        -p 80
-        -R http://localhost:443/
-
-    (Setting up a single proxy instance and using iptables to redirect to it
-    works as well)
