drop psgi_return, httpd/async and GetlineBody

Now that psgi_yield is used everywhere, the more complex
psgi_return and it's helper bits can be removed.  We'll also fix
some outdated comments now that everything on psgi_return has
switched to psgi_yield.  GetlineResponse replaces GetlineBody
and does a better job of isolating generic PSGI-only code.
