401f1debc5 common: clean up json routine locations.
We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.

Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

312751075c lightningd: save outgoing information for more forwards.
There's one case where we can present more infomation, so do that, and
fix documentation.

3a1a7eb93f wallet: allow saving forwarding scid even if we don't have amount.
They're not logically connected: we can know where they wanted to
go, but we didn't send it.

Where possible, it's the scid *they asked for*; otherwise, it's the
scid or fallback to the alias, but do this in the *caller*, not by
overriding inside wallet_forwarded_payment_add.

669bca4a02 ld: Use the local alias in the htlc_accepted hook
If we have no real short-channel-id this is the best we can do. Use
the local one since we can be sure we have assigned one.

517828adb2 lightningd: don't print nasty message when onchaind fails partially-failed HTLC
1. We set an outgoing htlc's `failonion` when we get a commitment_signed.
2. We don't transfer it to the corresponding incoming HTLC until we send
   commitment_signed and receive revoke_and_ack (meaning, outgoing htlc is
   completely dead).
3. If between these steps we go onchain, onchaind (after 3 blocks) tells us
   to fail the HTLC.
4. hout->failonion is set, but hout->hin has not been failed yet.  We
   do a sanity check and print a nasty message, and fail it with
   WIRE_PERMANENT_CHANNEL_FAILURE instead of relaying the error.

So handle this case explicitly.

36a2491a89 json: fix up msat amounts in non-_msat fields.
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".

2526e804f7 doc: big BOLT update to incorporate warnings language.
We do this (send warnings) in almost all cases anyway, so mainly this
is a textual update, but there are some changes:

1. Send ERROR not WARNING if they send a malformed commitment secret.
2. Send WARNING not ERROR if they get the shutdown_scriptpubkey wrong (vs upfront)
3. Send WARNING not ERROR if they send a bad shutdown_scriptpubkey (e.g. p2pkh in future)
4. Rename some vars 'err' to 'warn' to make it clear we send a warning.

This means test_option_upfront_shutdown_script can be made reliable, too,
and it now warns and doesn't automatically close channel.

bddd3694fa coin_mvt: record fees for an outbound htlc
If we initialized the payment, the fees are the entire fee-chain
(final hop amount - starting hop amount)

If it's a payment we routed, the fees are the diff between the
inbound htlc and the outbound (net gain by this routing)

Added to database so data persists nicely.

We record the amount of fees collected for a routed payment. For
simplicity's sake on the data agg side, we record the fee payment on
*BOTH* the incoming htlc and the outgoing htlc. Note that this results
in double counting if you add up the fees from both an in-routed and
out-routed payment.

4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.
