Currently it will be used for onion replies, but we can use it for offers
and invoices in future, if we want to avoid revealing our node_id.

This expects the caller to create the TLVs to put in each hop; it
simply creates the onion and sends it.

We put this in reply paths, so we can tell if they are used. This lets us
avoid responding unless the correct reply path is used.

One change from the obsolete version handling, gossipd will no longer send
forwarding onion msgs to lightningd, but will forward it directly.
That was the effect before, anyway.

It was really different from the way we decide the overall state of a
`pay` command's output. Now we use a more similar state decision,
based on collecting all states and checking them at the end to
determine the outcome.
We were checking against the wrong enum value, resulting in an
erroneous `pending` state as a final result.
Changelog-Fixed: pay: `pay` would sometimes misreport a final state of `pending` instead of `failed`
We had sent->path be a list of node_ids, but it makes more sense as
pubkeys so we can avoid conversion. Also, I find it easier to think
about (especially creating backwards paths) if we include *ourselves*
as the first element in the path.

sendonionmessage is going to be the new one, and do much *less*.
As this is an internal experimental-only API, no deprecation cycle
required.

offers contain an x-only pubkey: to route to them to need to know the
02 vs 03 prefix. If they're in the gossmap it's easy, but if they're
a directly-connected peer it's harder. We used to have
sendonionmessage tweak the key if it found a peer with the matching
key, but this was always a hack.
It turns out that we try to connect to the node anyway, which is
a noop if it's already connected. So try connecting to the other
parity if the first one fails.
Also, this registers when we fail to connect, and returns an error
rather than waiting for timeout.

We never tested that we can correctly unwrap on the next step after
unblinding: it failed because we mangled the onion in place! Fix that.

This is best-practice (to ensure prototypes match up), but there were a
few places we didn't (at least, directly). Make it a requirement,
either of form "foo.h" or <dir/foo.h>.
The noise is the change to our print templates.

Changelog-Added: `close` now notifies about the feeranges each side uses.
This was just a minor leak, found by CI for
test_openchannel_hook_chaining. We didn't call negotiation_aborted
which frees various fields: negotiation_failed() does that for us.

Changelog-Added: Protocol: We now send and support channel_type in channel open (not dual-funding though).
Currently we actually insist it's the default, but in future it could be

We also need to tell openingd what the channel_type was, if we resume
via openingd_funder_complete().
