centralize body => IO conversion logic

Since EventMachine and Rev shared the same logic for optimizing
and avoiding extra file opens for IO/File-ish response bodies,
so centralize that.

For Ruby 1.9 users, we've also enabled this logic so ThreadPool,
ThreadSpawn, WriterThreadPool, and WriterThreadSpawn can take
advantage of Rainbows::DevFdResponse-generated bodies while
proxying sockets.
