Temporarily disable sendpay_blinding test which uses obsolete onionmsg;
there's still some debate on the PR about how blinded HTLCs will work.
Changelog-EXPERIMENTAL: onionmessage: removed support for v0.10.1 onion messages.

Before this PR, there was no io_loop after shutdown_subdaemons and client side raised a
general `Connection to RPC server lost.`
Now we test the more specific `Channel forgotten before proper close.`, which is good!
BTW, this test was added recently in PR #4599.
It runs 6 nodes: under valgrind this ends up consuming 5.3 GB RSS. By
stopping nodes between, we peak about 1G RSS.
Measured using:
(while true; do echo $(for i in 4 5 6; do ps uh | tr -s ' ' | cut -d\ -f$i | tally; done); sleep 5; done)&
(Which measures my other processes as well, but that's only about 100M).

This surprised me, since the CHANGELOG for [0.8.2] said:
We now announce multiple addresses of the same type, if given. ([3609](https://github.com/ElementsProject/lightning/pull/3609))
But it lied!

October was the date Torv2 is no longer supported by the Tor Project;
it will probably not work at all by next release, so we should remove
it now even though it's not quite the 6 months we prefer for
deprecation cycles.
I still see 110 nodes advertizing Torv2 (vs 10,292 Torv3); we still
parse and display it, we just don't advertize or connect to it.

We're about to require that fundchannel_complete() take a PSBT, where it
does sanity checks to avoid this error, making this a difficult mistake

Fails liquid-regtest otherwise; liquid tends to hit the dust limit
earlier than non-liquid tx, and MPP exacerbates this by divvying up
payments into dusty bits then attempting to shove them through the same
channel, hitting the dust max. The MPP then fails as not all the parts
were able to arrive at their destination.
Let's make this a softer launch by just warning on the channel til the
feerates go back down.
You can also 'fix' this by upping your dust limit with
the `max-dust-htlc-exposure-msat` config.

Changelog-EXPERIMENTAL: bolt12: `vendor` is deprecated: the field is now called `issuer`.
We always allocate a new `struct command` when we get a full JSON
object from stdin:
b2df01dc73/plugins/libplugin.c (L1229-L1233)
If it happens to be a notification, we pass the `struct command` to
the handler, and not free it ourselves:
b2df01dc73/plugins/libplugin.c (L1270-L1275)
There are only nine points in `plugins/libplugin.c` where we `tal_free`
anything, and only one of them frees a `struct command`:
b2df01dc73/plugins/libplugin.c (L224-L234)
The above function `command_complete` is not appropriate for
notification handlers; the above function sends out a response
to our stdout, which a notification handler should not do.
However, as-is, it does mean that notification handling leaks
`struct command` objects, which can be problematic if we ever
have future built-in plugins which are significantly more
dependent on notifications.
This commit changes notification handlers to return
`struct command_result *`, because possibly in the future
notification handlers may want to perform `send_outreq`, so we
might as well use our standard convention for callbacks, and
to encourage future developers to check how to properly
terminate notification handlers (and free up the
`struct command`).
We also now provide a `notification_handled` function which a
notification handler must eventually call, as well as a
`notification_handler_pending` which is just a snowclone of
`command_still_pending`.
