We were counting the attempts including the root payment, which
resulted in an off-by-one error with the `test_pay_low_max_htlcs`
test. Counting the children of the root payment after the presplitter
had a go is the correct way to do it, since at that time we only have
one level in the tree, no need to recurse and potentially count
ourselves.
This was triggered by having some part being started after the overall
command already gave up, cleaning up the `cmd` context from which the
routehints were allocated. The early exit of the command, as a result
from a terminal state does not guarantee that no later attempt will
try to find a route, especially if the attempt was started before we
knew that it is doomed.
Otherwise our schema is pretty meaningless, since invalid decodes
can have missing "required" fields.
Also fix a typo "blinded_payindo".

Changelog-Experimental: JSON-RPC: `decode` now gives a `valid` boolean (it does partial decodes of some invalid data).
As mentioned in previous commits: "result" must be an object,
and anything else is an antipattern.

This is hard to parse, and not extensible in future, and disagrees with
the man page (and caught by schema).
Technically this is an API break, but it can't be done neatly anyway
and it's unlikely someone is relying on this today :(

Changelog-Changed: JSONRPC: `autocleaninvoice` now returns an object, not a raw string.

Changelog-Changed: Plugins: `fundchannel` and `multifundchannel` will now reserve funding they use for 2 weeks instead of 12 hours.
I don't know why it thinks that blockheight is INT_MAX, but
we shouldn't wait forever anyway.

1. We don't need to check for NULL before tal_count(NULL).
2. Use of json_for_each_arr iterator is probably better.
3. Weird indent fixed.

Users are more upset recently with the cost of unilateral closes
than they are the risk of being cheated. While we complete our
anchor implementation so we can use low fees there, let's
get less aggressive (we already have 34 or 18 blocks to close
in the worst case).
The changes are:
- Commit transactions were "2 CONSERVATIVE" now "6 ECONOMICAL".
- HTLC resolution txs were "3 CONSERVATIVE" now "6 ECONOMICAL".
- Penalty txs were "3 CONSERVATIVE" now "12 ECONOMICAL".
- Normal txs were "4 ECONOMICAL" now "12 ECONOMICAL".
There can be no perfect levels, but we have had understandable
complaints recently about how high our default fee levels are.
Changelog-Changed: Protocol: channel feerates reduced to bitcoind's "6 block ECONOMICAL" rate.

Changelog-Added: Plugins: `funder` plugin now has new command `funderupdate` which will show current funding configuration and allow you to modify them
Behold! An immaculately concepted plugin for configuring your node to do
amazing things*
*fund channel open requests
Changelog-Added: Plugins: Add `funder` plugin, which allows you to setup a policy for funding v2 channel open requests. Requres --experimental-dual-fund option
If we only add a single input/output for the funding transaction,
we'll only call openchannel_update once, which results in
a crash because the dest->state will never advance to
MULTIFUNDCHANNEL_UPDATED;
Instead, we update to UPDATED before we check for doneness.
It's unlikely but possible that a race condition will result in us not
being at the 'secured' state yet here.
Crashlogs. All required msgs are received (in order)
from peers, but the crash suggests they weren't relayed/processed by the
spender plugin in the order received.
WIRE_TX_SIGNATURES is passed the the plugin via a notification;
WIRE_COMMITMENT_SIGNED is returned as the result of an RPC call.

Fixes#4455
You can now activate dual-funded channels using the
`--experimental-dual-fund` flag
Changelog-Changed: Config: `--experimental-dual-fund` runtime flag will enable dual-funded protocol on this node
There is little point in faking a self-payment, but we should also not
crash :-)
Fixes#4438
Changelog-Fixed: keysend: Keysend returns an error when a self-payment is requested
