Upstream: trailers support, u->conf->pass_trailers flag. Basic trailer headers support allows one to access response trailers via the $upstream_trailer_* variables. Additionally, the u->conf->pass_trailers flag was introduced. When the flag is set, trailer headers from the upstream response are passed to the client. Like normal headers, trailer headers will be hidden if present in u->conf->hide_headers_hash.
