We need to remember this in the db (it's a P2WSH for option_anchor_outputs),
and we need to set nSequence to 1 to spend it.

Anchor outputs break many assumptions in our tests:
1. Remove some hardcoded numbers in favor of a fee calc, so we only have to
change in one place.
FIXME: This should also be done for elements!
2. Do binary search to get feerate for a given closing fee.
3. Don't assume output #0: anchor outputs perturb them.
4. Don't assume we can make 1ksat channels (anchors cost 660 sats!).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This also means we subtract 660 satoshis more everywhere we subtract
the base fee (except for mutual close, where the base fee is still
used).

This is best done by passing `struct bitcoin_signature` around instead
of raw signatures. We still save raw sigs to the db, and of course the
wire protocol uses them.

HTLC fees increase (larger weight), and the fee paid by the opener
has to include the anchor outputs (i.e. 660 sats).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This is the same way we handle option_static_remotekey, which
is also sticky (if negotiated at opening time, it always applies).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This simplifies our test matrix, as we never have to handle talking
to peers that specify one but not the other.
This is particularly important for option_anchor_outputs which
assumes option_static_remotekey.

Changelog-Added: `listfunds` now has a `redeemscript` field for p2sh-wrapped outputs.
This is what txsend does, only we have a psbt so we have
to change the db interface to take a wally_tx.

It's currently always 0, but it won't be once we replace txprepare.

Changelog-Added: JSON-RPC: `fundchannel` has new `outnum` field indicating which output of the transaction funds the channel.
My testing shows that I received errors which turned out to be fatal ("/usr/libexec/c-lightning/lightning_connectd: libbacktrace: no debug info in ELF executable") when I had two `bind-addr=...` settings in my config file, which the instructions insinuated since c-lightning would already have been installed and runnable (therefore, already having a bind-addr).

Changelog-Fixed: pay: Correct a case where we put the sub-payment value instead of the *total* value in the `total_msat` field of a multi-part payment.
Only advance through routehints if no route was found at all, or if the
estimated capacity at the routehint is lower than the amount that we
have to send through the routehint.
Changelog-Fixed: pay: Be less aggressive with forgetting routehints.
The worst effect is that unpublished nodes are harder to pay, but
even published ones make us do unnecessary work, since we are
losing routehints from the published ones that could help us
actually route better to them.
On my test machine, we queried bitcoind before the close tx was sent:
```
# When output is spent, it should give us null !
txo = l1.rpc.call("getutxout", {"txid": txid, "vout": 0})
> assert txo["amount"] is txo["script"] is None

We were running the integration tests and the install tests with every
test-group, which doesn't increase test coverage at all. So now we bundle them
with the source check which are short and remove them from the overloaded
configurations.
