refactor response body handling for sendfile(2)

This hopefully allows the "sendfile" gem to be required
anywhere in the Rainbows!/Unicorn config file, and not
have to be required via RUBYOPT or the '-r' command-line
switch.

We also modularize HttpResponse and avoids singleton methods
in the response path.  This (hopefully) makes it easier for
individual concurrency models to share code and override
individual methods.
