Comment:

 (In [4467]) 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
