Subject: Handle files from ActionDispatch::Static with Rack::Sendfile (fixes
 #5225)

This makes rails behave properly when you serve static assets
and you have X-Sendfile headers enabled. Nevertheless in most
cases you should not rely on that and serve static assets with
a webserver like Apache or Nginx (as you already have it in
place anyway if you use X-Sendfile)
