32c7c133f4 common/sphinx: make onionpacket.routinginfo a dynamic member.
Still asserts that it's the standard size, but makes it a dynamic
member.  For simpliciy, changes the parse_onionpacket API (it must be
a tal object now, so we might as well allocate it here to catch all
the callers).

b2a5cf422f jsonrpc: Forward errors on malformed requests to cli
We were masquerading errors when parsing the request by reporting only
a bogus malformed `id` field in the response, when the real issue was
that we were unable to parse the request in the first place (which
caused the null-id error to be returned).

Fixes #4238

695a8bd868 lightningd: split onion_message hook.
Only way to be sure that plugins don't accidentally respond to onion_message
sent via reply path from another message (which would potentially leak our
identity!).

To quote BOLT #7 (Onion Messages) in the offers PR:

```markdown
The reader:
- MUST ignore any message which contains a `blinding` which it did not expect, or does not contain
  a `blinding` when one is expected.
...
`blinding` is critical to the use of blinded paths: there are various
means by which a blinded path is passed to a node.  The receipt of an
expected `blinding` indicates that blinded path has been used: it is
important that a node not accept unblinded messages when it is expecting
a blinded message, as this implies the sender is probing to detect if
the recipient is the terminus of the blinded path.

Similarly, since blinded paths don't expire, a node could try to use
a blinded path to send an unexpected message hoping for a response.
```

fb295ffb51 plugin: sort topological candidates by specified order.
We previously registered hooks up in who-replies-to-getmanifest-first

forgotten by specifying the plugins manually in their configuration or
cmdline.  This was an excellent consideration by @mschmook.

8a8dabaa58 feat: adds state change cause and message
This adds a `state_change` 'cause' to a channel.
A 'cause' is some initial 'reason' a channel was created or closed by:

  /* Anything other than the reasons below. Should not happen. */
  REASON_UNKNOWN,
  /* Unconscious internal reasons, e.g. dev fail of a channel. */
  REASON_LOCAL,
  /* The operator or a plugin opened or closed a channel by intention. */
  REASON_USER,
  /* The remote closed or funded a channel with us by intention. */
  REASON_REMOTE,
  /* E.g. We need to close a channel because of bad signatures and such. */
  REASON_PROTOCOL,
  /* A channel was closed onchain, while we were offline. */
  /* Note: This is very likely a conscious remote decision. */
  REASON_ONCHAIN

If a 'cause' is known and a subsequent state change is made with
`REASON_UNKNOWN` the preceding cause will be used as reason, since a lot
(all `REASON_UNKNOWN`) state changes are a subsequent consequences of a prior
cause: local, user, remote, protocol or onchain.

4ea9d9e928 df: Pass new feerate options through to plugin, set reasonable bounds
We let the plugin decide what feerate to accept/whether or not to add
funds to the open. To aid this decision, we also send the plugin what we
(c-lightning) currently have as our max and min acceptable feerates.

We also now use these as our default for max/min acceptable feerate
range when sending an openchannel offer to a peer.

In the future, it might be a good idea to make these more easily
changeable, either via a config setting (?) or a command param.

21122af3a8 dev-force-features: adds a second valid format for forcing features
The previous dev-force-features forced you to explicitly declare every
desired feature bit in an array, for each set.

Here, we allow you to also denote adding/subtracing a feature bit
by just passing in the number of the bit to flip and the direction to
turn it. e.g.

	'dev-force-features': '+223'

Will turn on opt_dual_fund/odd.

	'dev-force-features': '-16'

Will flag off opt_basic_mpp.
