It's very similar to the previous, but there are a few changes:
1. The enctlv fields are numbered differently.
2. The message itself is a different number.
The onionmsg_path type is the same, however, so we keep that constant
at least.
The result is a lot of cut & paste, but we will delete the old one
next release.

This is from 6e99c5feaf60cb797507d181fe583224309318e9
We renamed the enctlv field to encrypted_recipient_data in the spec, and the
new onion_message is message 513. We don't handle it until the next patch.
Two renames:
1. blinding_seed -> blinding_point.
2. enctlv -> encrypted_recipient_data.
We don't do a compat cycle for our JSON APIs for these experimental
features only used by our own plugins, we just rename.

Changelog-Changed: pay: The route selection will now use the log-propability-based channel selection to increase success rate and reduce time to completion
We bias by channel linearly by capacity, scaled by median fee.
This means that we effectively double the fee if we would use the
entire capacity, and only increase it by 50% if we would only use
1/2 the capacity.
This should drive us towards larger channels.

Changelog-Changed: Plugins: `pay` now biases towards larger channels, improving success probability.
sendonionmessage can fail when sending a reply, either because
the reply had a bad first peer, or because it went offline. The
latter happens in CI, which is how I found this.
Also fixed typo "onio" -> "onion".

Changelog-Added: pay: Payment attempts are now grouped by the pay command that initiated them
Changelog-Fixed: pay: `listpays` returns payments orderd by their creation date
Changelog-Fixed: pay: `listpays` no longer groups attempts from multiple attempts to pay an invoice
So far we've always been deferring the deletion, retry and early abort
logic to `sendonion` and `sendpay` which do not have the context to
decide if a call is legitimate or not (they were mostly based on
heuristics). By calling `listsendpays` for the invoice's
`payment_hash` we can identify what our `groupid` should be, but more
importantly we can also abort if another payment is pending or a prior
attempt has already succeeded.
We keep the now-removed chains field, and in deprecated mode, we set it.

Changelog-EXPERIMENTAL: bolt12: `chains` in invoice_request and invoice is deprecated, `chain` is used instead.
Main changes are:
1. Uses point32 instead of pubkey32.
2. Uses issuer instead of vendor.
3. Uses byte instead of u8.
4. blinded_path num_hops is now a byte, not u16 (we don't use that yet!).

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`.

Changelog-Experimental: Protocol: Updated onion_message support to match updated draft specification (with backwards compat for old version)
We carefully copied the buffer, but the tok is inside an array. We get away
with it for now, but with coming changes it gets freed. We need to copy
the token and all the tokens within it.

This comes in via the onion_message_ourpath hook, and we identify the
path by checking the node alias it came to (vs the obsolete version
which used the blinding).

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*.

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 make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds). This scheme
follows the latest draft, in which features are flagged compulsory.
We also add several helper functions.
Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.
