We had json_add_amount_msat_only(), which was designed to be used to
print out msat fields, if we had sats.
However, we misused it, so split it into the three different cases:
1. json_add_amount_sat_msat: We are using it correctly, with a field called
xxx_msat.
2. json_add_amount_sats_deprecated: We were using it wrong, so deprecate
the old field and create a new one which does end in _msat.
3. json_add_sats: we were using it to hand sats as a JSON parameter to an
interface, where "XXXsat".

We were setting it on the root, but that doesn't get handed to
sendpay. Our schema doesn't *require* bolt11, either, so this was
missed (there could be a *bolt12* instead).

Changelog-Fixed: JSON-RPC: `listpays` always includes `bolt11` or `bolt12` field.
This is what LND does, and it's better for upper layers than trying to
twist our maxfeepercent / exemptfee heuristics to suit.
(I don't remember who complained about this, sorry!)
I'm doing this now because I want to add YA parameter next!

Changelog-Added: JSON-RPC: `pay` has new parameter `maxfee` for setting absolute fee (instead of using `maxfeepercent` and/or `exemptfee`)
I think the new pay command has proven itself in the last 18 months!
Also various pay tests took "compat" then didn't use it, so clean them
up.

I removed these prematurely: we *haven't* had a release since
introducing them!
This consists of reverting d15d629b8b
"plugins/fetchinvoice: remove obsolete string-based API." and

API. "onion_messages: remove obs2 support."
Some minor changes due to updated fromwire_tlv API since they
were removed, but not much.

Changelog-Added: Protocol: you can now alter the `htlc_minimum_msat` and `htlc_maximum_msat` your node advertizes.
We still use the channel hint here (as it's the only option), we just
warn about lack of capacity.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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.

This restores the behaviour prior to `lightningd: use our cached
channel_update for errors instead of asking gossipd.`, where gossipd
would refuse to give us channel_updates for unannounced channels.

If the HTLCs are completely negotiated, we can get a channel break when
we mine a pile of blocks. This is mainly seen with Postgres, due to the db
speed.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
If we fund a channel between two nodes, then mine all the blocks to
announce it, any other nodes may see the announcement before the
blocks, causing CI to complain about "bad gossip":

We seem to hit a race between manual reconnect (with address hint) and an automatic

channeld can't do it any more: it's using local sockets. Connectd
can do it, and simply does it by type.
Amazingly, on my machine the timing change *always* caused
test_channel_receivable() to fail, due to a latent race.

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-Added: pay: Payment attempts are now grouped by the pay command that initiated them
