Upstream: duplicate headers ignored or properly linked.

Most of the known duplicate upstream response headers are now ignored
with a warning.

If syntax permits multiple headers, these are now properly linked to
the lists, notably Vary and WWW-Authenticate.  This makes it possible
to further handle such lists where it makes sense.
