We need to add some, since our internal representations of
htlc_maximum_msat round up, and we need to disable mpp which succeeds
in getting a payment through by splitting.
We also allow dev_routes to suppress invoice routehints altogether.

Based on setchannelfee, but expanded to allow setting max htlc amount (and others
in future?).
The main differences:
1. It doesn't change values which are not specified (that would be hard to
add fields to!)
2. It says exactly what all values are in any potentially changed channels.
Changelog-Added: JSON-RPC: new `setchannel` command generalizes `setchannelfee`.

This is htlc_maximum_msat in BOLT 7 speak, but this name matches our existing
fields and is clearer in this context.

We used to calculate it ourselves. Unfortunately this needs to
be done in several places, since new_channel() isn't used to fully
create a channel in the case of dual funding :(

Things allocated by libwally all get the tal_name "wally_tal",
which cost me a few hours trying to find a leak.
In the case where we're making one of the allocations the parent
of the others (e.g. a wally_psbt), we can do better: supply a name
for the tal_wally_end().
So I add a new tal_wally_end_onto() which does the standard
tal_steal() trick, and also changes the (typechecked!) name.

Changelog-Removed: protocol: support for legacy onion format removed, since everyone supports the new one.
This is the cheapest algo I came up with that simply checks that the
same `remote_addr` has been report by two different peers. Can be
improved in many ways:
- Check by connecting to a radonm peers in the network
- Check for more than two confirmations or a certain fraction
- ...
Changelog-Added: Send updated node_annoucement when two peers report the same remote_addr.
Instead of doing this weird chaining, just call them all at once and
use a reference counter.
To make it simpler, we return the subd_req so we can hang a destructor
off it which decrements after the request is complete.

For example, if you do:
```
./lightningd/lightningd --network=regtest --experimental-websocket-port=19846
```
Then you're trying to reuse the normal port as the websocket port, but this
only fails at *listen* time, when we activate connectd. Catch this too.
Fixes incorrect fatal() message, too.

This was causing journal_entries to show up in the accountant plugin,
since we don't emit events for unconfirmed events until they're actually
confirmed onchain.
Useful for accounting for missed/historical channel opens, to figure out
what the actual sat contribution from each peer is at a utxo level
Changelog-Added: JSONRPC: `listpeers` now includes a `pushed_msat` value. For leased channels, is the total lease_fee.
Only shows up on delayed to us outputs, but nice to have anyway.
It's missing for channel index destined deposits, maybe nice to add at
some point in the future; right now you can figure out which close a
wallet deposit comes from via the channel close txid
There is no "wallet_lib_headers" variable in wallet/Makefile
Likewise, there were two "lightningd_headers", a couple of unused
variables and some other nonsene in lightningd/Makefile
All build flags and (experimental) options make it hard to find
out what features are supported or enabled.
And the undocumented `--list-features-only`, does not account for all
our featurebits, for example bit 55 (keysend).
Changelog-Added: JSON-RPC: `getinfo` result now includes `our_features` (bits) for various Bolt #9 contexts
If this field is missing for whatever reason (weird db state?)
clightning will crash when listing invoices.

If we call update_channel_from_inflight *twice* with the same inflight, we
will get bad results. Using tal_steal() here was a premature optimization:

Changelog-Changed: JSON_RPC: `sendcustommsg` now works with any connected peer, even when shutting down a channel.
