This will make it possible to do RBF, since we can re-start the opening
process in dualopend while waiting for lock-in.
Note the new channel states are being used, DUALOPEND_INIT and
DUALOPEND_AWAITING_LOCKIN, to differentiate from openingd/channeld opens
v2 channel opens are going to happen over in dualopend. In order
to make sure that these don't end up in the wrong place/to keep track of
the difference between "waiting for sigs" and "have merely initiatlized
a channel", we add two new states to the channel state machine.
A channel that 'originates' in dualopend will only ever arrive at
channeld in the state CHANNELD_NORMAL.
Since this all stays in dualopend/dual_open_control, we can hold
onto the openchannel_signed command to wait for a response here locally.
Previously we were splitting across the channeld/openingd boundary.
We used this for dual funded opens, to track the receipt of signatures.
We're moving all of this over to dualopend now, however, so we no longer
need the PSBT in channeld.
As per lastest revision of the spec, we can specify amounts in invoice
requests even if the offer already specifies it, as long as we exceed
the amount given. This allows for tipping, and amount obfuscation.

Means a reshuffle of our logic: we want to multiply by quantity before
conversion for maximum accuracy.

This avoids a footgun where they create an offer then we can't create
the invoice because they don't have a converter plugin.

1. The field *expiry_time* is actually called *expires_at*.
2. The description field is missing.
3. The bolt11 field is missing.

This is experimental for now, but can eventually deprecated
'decodepay' and even decode other kinds of messages.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Our new "decode" command will also handle bolt11. We make a few cleanups:
1. Avoid type_to_string() in JSON, instead use format functions directly.
2. Don't need to escape description now that JSON core does that for us.

We split `send_invoice` offers inoo offerout (for want of a better name).
This simplifies the API.
Also took the opportunity to move the `vendor` tag to immediately
follow `description` (our tests use arguments by keywords, so no
change there).

The previous onion_message code required a confirmed, not-shutting-down
channel, not just a connection. That's overkill; plus before widespread
adoption we will want to connect directly as a last resort.

refund offers are implied send_invoice offers. And send_invoice offers
are implied single-use offers, though it can also make sense to have
a non-send_invoice offer be single-use.

When looking for a pytest executable we should be looking for the ones
that `pip` installs in a virtualenv (`pytest` and `py.test`) before we
look for the ones that `apt` installs system-wide (`pytest3` and
`py.test3`) because these may not be part of the virtualenv that all
other packages are installed in.
This is required if we want to create a "bouncer" plugin (in my copious free time!)

Changelog-Added: JSON-RPC: `invoice` now takes an optional `cltv` parameter.
