Subject: [PATCH 01/12] staticbackup: don't use wireaddr_internal.
This is an internal type: it has no API guarantees (indeed, I'm about
to change it, which is how I discovered scb was using it).
Fortunately for every case we care about, it is actually a wireaddr
(in theory the peer can connect locally using a local socket, but this
is mostly for testing and is a very strange setup, and so simply don't
do scb for those).
In this case, the wire encoding is a single byte followed by the
wireaddr, so open-code that in scb_wire.csv for compatibility.

Subject: [PATCH 02/12] connectd: clean up add_gossip loops.
This contained cut & paste code, and it wasn't clear to me that
the first loop included DNS entries with IPv6 entries.
Instead, allow the iterator to take multiple types, and use
a switch statement so compile will break as new types are added.

Subject: [PATCH 03/12] common/wireaddr.h: simplify parse_wireaddr API.
1. Make it the standard "return the error" pattern.
2. Rather than flags to indicate what types are allowed, have the callers
check the return explicitly.
3. Document the APIs.

Subject: [PATCH 04/12] connectd: don't advertise websocket addresses.
I never really liked this hack: websockets are useful, advertizing
them not so much.
Note that we never actually documented that we would advertize these!
Changelog-EXPERIMENTAL: Protocol: Removed support for advertizing websocket addresses in gossip.

Subject: [PATCH 06/12] wireaddr: clean up option parsing, support `dns:`
prefix directly.
This is a major cleanup to how we parse addresses.
1. parse_wireaddr now supports the "dns:" prefix to support dns records (type 5).
2. We are less reliant on separate_address_and_port() which gets confused by
that colon.
3. We explicitly test every possible address type we can get back from
parsing, and handle them appropriately.
We update the documentation to use the clearer HOSTNAME vs DNS prefixes now
we also have `dns:` as a prefix.
Changelog-Added: Config: `bind` can now take `dns:` prefix to advertize DNS records.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Changelog-Deprecated: Config: `announce-addr-dns`; use `--bind-addr=dns:ADDR` for finer control.

Subject: [PATCH 08/12] lightningd: deprecate weird listening options.
These are only likely to confuse users, by silently changing behavior.
Changelog-Deprecated: Config: bind-addr=xxx.onion and addr=xxx.onion, use announce=xxx.onion (which was always equivalent).
Changelog-Deprecated: Config: addr=/socketpath, use listen=/socketpath (which was always equivalent).
