When we used to allow cmd to be NULL, we had to hand the plugin
everywhere. We no longer do.
1. Various jsonrpc_ functions no longer need the plugin arg.
2. send_outreq no longer needs a plugin arg.
3. The init function takes a command, not a plugin.
4. Remove command_deprecated_in_nocmd_ok.

We were dereferencing the first character of the id, (always '"') which meant
everything was id 34.

Changelog-Fixed: `pay`: debug logging now uses correct JSON ids.
This means we replace p->cmd with an auxillary command after we've
finished, so we have a valid command to use.
It also means we weave `struct command_result` returns back through
all the callers.

Sometimes we want to clean up *after* a command has completed, but
we're moving to a model where all libplugin operations require a
`struct command`. This adds `aux_command` to create an
independent-lifetime command with the same id.

I started getting "WIRE_TEMPORARY_CHANNEL_FAILURE: Too many HTLCs" after

This was nice (it found some bugs in injectpaymentonion's handling of
local errors, and in xpay's reporting), but shouldn't happen.

Start with a random capacity (linear prob), and remember in-progess

Our gossmap_store uncompresser generates nodeids with well-known
privkeys, so we can decrypt and respond to HTLCs sent to such nodes.
By replacing channeld with a fake, we can connect a node to another
node, but then once the channel is established, allow payments to be
sent into the generated network, and respond appropriately.
This minimal version handles MPP timeouts, but doesn't insert any
delays or runtime capacity for channels.

The original complaint which caused my investigation was the 100% CPU
consumption of connectd, which we traced to the queue to gossipd.
However, the issue is not really connectd's overproduction, but
gossipd's underconsumption, probably caused by its own queueing issues
with the trace messages to lightningd, which the prior patch fixed.
Nonetheless, gossipd *can* get busy, and if we were to ask multiple
nodes for full gossip, we could see a few hundred thousand messages
come it at once. Hence I'm increasing the warning limit to 250,000
messages.
This commit is also where we attach the Changelog message, even
though it's really "common/msg_queue: use membuf for greater efficiency."
and "gossipd: fix excessive msg_queue length from status_trace()" which
solved the problem.
Here's the backtrace from a previous debug patch:
```

Changelog-Fixed: `connectd` and `gossipd` message queues are much more efficient.
When this (very spammy) "handle_recv_gossip" message was changed
from debug to trace, the suppression code wasn't updated: we suppress
overly active debug messages, but not trace messages.
This is the backtrace from an earlier version of the "too large queue"
patch:
```

Without this, we have hardly any enforcement. This is why the schema
mistake fixed in the previous patches weren't spotted immediately.
The hard work was done by:
```
$ for f in lightning-*.json; do grep -v '^ "additionalProperties": false,' $f | bagto $f; done
$ for f in lightning-*.json; do sed 's/"properties": {/"additionalProperties": false, "properties": {/' $f | bagto $f; done
$ make fmt-schemas
```
Then checking where 'additionalProperties: true' had been turned to
false (we deliberately use it in some places where there are if
statements in the schema, or occasionally where there can be arbitrary
fields).

This allows the next patch (which makes the schemas stricter) to not
break our tests.
We add some missing fields (including dev fields, but they're empty and hidden),
and add a few minor clarifications and a spelling fix. Most of these are new
schemas for this release, so no mention in Changelog.

there's a failonion it was unparsable!
