Rusty Russell f00cc23f67 sphinx: rename confusing functions, ensure valid payloads.
"sphinx_add_hop" takes a literal hop to include,
"sphinx_add_modern_hop" prepends the length.  Now we always prepend a
length, make it clear that the literal version is a shortcut:

* sphinx_add_hop -> sphinx_add_hop_has_length
* sphinx_add_modern_hop -> sphinx_add_hop

In addition, we check that length is actually correct!  This means
`createonion` can no longer create legacy or otherwise-invalid onions:
fix tests and update man page to remove legacy usage.

Rusty Russell 6338758018 gossmap: make API more robust against future changes.
Many changes to gossmap (including the pending ones!) don't actually
concern readers, as long as they obey certain rules:

1. Ignore unknown messages.
2. Treat all 16 upper bits of length as flags, ignore unknown ones.

So now we split the version byte into MAJOR and MINOR, and you can
ignore MINOR changes.

We don't expose the internal version (for creating the map)
programmatically: you should really hardcode what major version you
understand!

Rusty Russell 5b58eda748 libplugin: mark the cmd notleak() whenever command_still_pending() called.
This is what we do in lightningd, which makes memleak much more forgiving:
you can hang temporaries off cmd without getting reports of leaks (also
when send_outreq called).

We remove all the notleak() calls in plugins which worked around this!
And avoid multiple notleak labels, since both send_outreq() and
command_still_pending() can be called multiple times.

Alex Myers 4167fe8dd9 gossip_store: fix offset error
The gossip_store version byte was unaccounted for in the initial traversal

skipped, potentially leading to gossip propagation issues downstream.

niftynei 30aa1d79fb bkpr: for zerconfs, we still wanna know you're opening a channel
We need a record of the channel account before you start sending
payments through it. Normally we don't start allowing payments to be
sent until after the channel has locked in but zeroconf does away with
this assumption.

Instead we push out a "channel_proposed" event, which should only show
up for zeroconfs.

niftynei 0617690981 coin_mvt/bkpr: add "stealable" tag to stealable outputs
If we expect further events for an onchain output (because we can steal
it away from the 'external'/rightful owner), we mark them.

This prevents us from marking a channel as 'onchain-resolved' before
all events that we're interested in have actually hit the chain.

Case that this matters:
Peer publishes a (cheating) unilateral close and a timeout htlc (which
we can steal).
We then steal the timeout htlc.

W/o the stealable flag, we'd have marked the channel as resolved when
the peer published the timeout htlc, which is incorrect as we're still
waiting for the resolution of that timeout htlc (b/c we *can* steal it).

niftynei a45da63280 bkpr: pass the node_id over for channel_opens, add to account
it's nice to know what node your channel was opened with. in theory we

channels disappear after they've been closed for a bit. it's better to
just save the info.

information

niftynei a3d82d5a01 bkpr: exclude non-wallet events in the balance snapshot
Anchor outputs are ignored by the clightning wallet, but we keep track
of them in the bookkeeper. This causes problems when we do the balance
checks on restart w/ the balance_snapshot -- it results in us printing
out a journal_entry to 'get rid of' the anchors that the clightning node
doesnt know about.

Instead, we mark some outputs as 'ignored' and exclude these from our
account balance sums when we're comparing to the clightning snapshot.

First, connectd tells us the peer has connected, and we call the connected hook,
and if it says it's fine, we are actually connected and we fire off notifications.

Of course, we could be disconnected while in the connected hook, and that would
mean we tell people about a connection which is no longer current.

Make this clear with a tristate: if we're not marked disconnected by
the time the hooks finish, we're good.  It also gives us a cleaner
