Changeset 4467

Message:

Produce the X-Forwarded-For: header in vcl_recv, so people can tweak
as they want.

Append to already existing header if possible.

NB: If you return early from your own vcl_recv, without pasting these
lines in top of your vcl_recv, your backend gets no X-F-F header.

Fixes #601
Fixes #540
