899ec2b3d4 JSON API: fix up two existing warnings to be conformant.
Technically an API break, but nobody relies on these I hope!

Note that the feerates warning was buried inside the style object:
it should be top-level.

5776a33116 paymod: Activate paymod and move legacy pay to legacypay command
As suggested during the paymod-03 review it is better to activate the new code
right away, and give users an escape hatch to use the legacy code instead. The
way I implemented it allows using either `legacypay` or `pay` and then set
`legacy` to switch to the other implementation.

Changelog-Added: JSON-RPC: The `pay` command now uses the new payment flow, the new `legacypay` command can be used to issue payment with the legacy code if required.

01a475161d paymod: Implement keysend sending support as a native RPC command
This makes use of the payment modifier structure to just add the preimage to
the TLV payload for the last hop.

Changelog-Added: JSON-RPC: The `keysend` command allows sending to a node without requiring an invoice first.

6a75497eb2 pytest: Add a compat() fixture allowing checks for specific flags
Since we change the interface for `pay` and `paystatus` we need a way to

1708fb91e5 wallet: clean up json output creation, part 2.
It looked like we weren't printing the address on closing outputs.

But we are, because the 'scriptPubkey' field is in the 'outputs' db
table since 0.7.3 (66a47d2761).

So make the logic clearer, and remove a completely bogus comment (UTXOs
with closing_info are definitely spendable!).

We export the json_add_utxos() for future use, too.

7aa8ffa2a0 bitcoin: add weight calculation helpers.
These are pulled from wallet/wallet.c, with the fix now that we grind sigs.

This reduces the fees we pay slightly, as you can see in the coinmoves changes.

I now print out all the coin moves in suitable format before we match:
you only see this if the test fails, but it's really helpful.

fc2561fd9e pytest: fix test breakage added by d0c85033d2
By setting nLocktime to the current block, the reorg test
"test_funding_reorg_remote_lags" actually drops the funding transaction
entirely when a reorg happens.

Except the 1 in 10 cases where nLocktime is randomly set to 1-10
blocks earlier.

This implies, strongly, that we hit "restart" too often on Travis.

2e9c387f45 coin_moves: update withdrawal logic to account for 'variable owner' txs
Our existing coin_moves tracking logic assumed that any tx we had an
input in belonged to *all* of our wallet (not a bad assumption as long
as there was no way to update a tx that spends our wallets)

Now that we've got `signpsbt` implemented, however, we need to be
careful about how we account for withdrawals. For now we do a best guess
at what the feerate is, and lump all of our spent outputs as a
'withdrawal' when it's impossible to disambiguate

5db69f1b41 lightningd/opening_control.c: Remove 'Try fundchannel_cancel again' error.
Changelog-Changed: `fundchannel_cancel` will now succeed even when executed while a `fundchannel_complete` is ongoing; in that case, it will be considered as cancelling the funding *after* the `fundchannel_complete` succeeds.

Let me introduce the concept of "Sequential Consistency":
All operations on parallel processes form a single total order agreed upon by all processes.

So for example, suppose we have parallel invocations of `fundchannel_complete` and `fundchannel_cancel`:

                          +--[fundchannel_complete]-->
                          |
    --[fundchannel_start]-+
                          |
                          +--[fundchannel_cancel]---->

What "Sequential Consistency" means is that the above parallel operations can be serialized as a single total order as:

    --[fundchannel_start]--[fundchannel_complete]--[fundchannel_cancel]-->

Or:

    --[fundchannel_start]--[fundchannel_cancel]--[fundchannel_complete]-->

In the first case, `fundchannel_complete` succeeds, and the `fundchannel_cancel` invocation also succeeds, sending an `error` to the peer to make them forget the chanel.

In the second case, `fundchannel_cancel` succeeds, and the succeeding `fundchannel_complete` invocation fails, since the funding is already cancelled and there is nothing to complete.

Note that in both cases, `fundchannel_cancel` **always** succeeds.

Unfortunately, prior to this commit, `fundchannel_cancel` could fail with a `Try fundchannel_cancel again` error if the `fundchannel_complete` is ongoing when the `fundchannel_cancel` is initiated.
This violates Sequential Consistency, as there is no single total order that would have caused `fundchannel_cancel` to fail.

This commit is a minimal patch which just reschedules `fundchannel_cancel` to occur after any `fundchannel_complete` that is ongoing.
