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.
