This allows using IO::Splice.copy_stream from the "io_splice"
RubyGem on recent Linux systems.  This also allows users to
disable copy_stream usage entirely and use traditional
response_body.each calls which are compatible with all Rack
servers (to workaround bugs in IO.copy_stream under 1.9.2-p180).
