I think this addresses the performance issue reported in Issue #6178
As noted there, a new commit from @masaori335 cleaned up the chunked data processing. The HTTP/2 implementation was relying on that to send empty DATA frames with the EOS bit set to finish the transaction instead of setting the EOS bit on the response header.
This PR detects methods and return codes that will not send a response body, so the HEADER frame can have the EOS bit set directly, and avoid the inactivity timeout.
