16134801ce 3750. [experimental] Partially implement EDNS EXPIRE option as described
in draft-andrews-dnsext-expire-00.  Retrivial of
                        remaining time to expiry from slave zones is supported.

                        EXPIRE uses an experimental option code (65002) and
                        is subject to change. [RT #35416]

b5f6271f4d 3744. [experimental] SIT: send and process Source Identity Tokens
(which are similar to DNS Cookies by Donald Eastlake)
                        and are designed to help clients detect off path
                        spoofed responses and for servers to detect legitimate
                        clients.

                        SIT use a experimental EDNS option code (65001).

                        SIT can be enabled via --enable-developer or
                        --enable-sit.  It is on by default in Windows.

                        RRL processing as been updated to know about SIT with
                        legitimate clients not being rate limited. [RT #35389]
