Subject: http_response: use kgio_syssend with MSG_MORE

If Content-Length is known, try to save some bandwidth by
corking the headers until the body is sendable.  This allows
us to avoid sending an extra packet for small HTTP responses.

This allows high-performance websites like YHBT.net to be served
faster!
