       stash original headers in env["unxf.{for,proto}"]
       
       This will allow applications to access private data in UnXF
       if they're UnXF-aware, but won't normally confuse applications
       that have had the Rack env mangled by UnXF

       unxf: avoid 400 errors
       
       We get XFF from real external traffic.  We just won't change
       anything in env if we can't trust the original REMOTE_ADDR or
       the XFF chain

       unxf: split out unxf! to allow usage outside of middleware
       
       Increasing Rack middleware use increases stack depth, which
       can hurt performance due to the Ruby GC scanning the stack.
       This allows users to use UnXF outside of the traditional
       environment.
