Rusty Russell 27220646c3 common/wire: move bitcoin-specific marshalling functions into bitcoin files.
We did this originally because these types are referred to in the bolts, and we
had no way of injecting the correct include lines into those.  Now we do, so
there's less excuse for this.

lisa neigut de86e29e16 coin moves: log all withdrawals when confirmed in a block
This moves the notification for our coin spends from when it's

We also add an 'informational' notice tagged as `spend_track` which
can be used to track which transaction a wallet output was spent in.

lisa neigut e9d26a46e0 coin moves: actually record the blockheight for all chain moves
Previously we were annotating every movement with the blockheight of
lightningd at notification time. Which is lossy in terms of info, and
won't be helpful for reorg reconciliation. Here we switch over to
logging chain moves iff they've been confirmed.

Next PR will fix this up for withdrawals, which are currently tagged
with a blockheight of zero, since we log on successful send.

Rusty Russell b0c9059602 tools/generate-wire: no more lonely messages!
When we have only a single member in a TLV (e.g. an optional u64),
wrapping it in a struct is awkward.  This changes it to directly
access those fields.

This is not only more elegant (60 fewer lines), it would also be
more cache friendly.  That's right: cache hot singles!

lisa neigut 0e20e3c5e7 df: rename 'funder' to 'opener'
Previously we've used the term 'funder' to refer to the peer
paying the fees for a transaction; v2 of openchannel will make
this no longer true. Instead we rename this to 'opener', or the
peer sending the 'open_channel' message, since this will be universally
true in a dual-funding world.

Christian Decker 8370a627bb invoice: Parse amounts without a multiplier as BTC not msats
The spec states that invoices with an amount, but lacking a multiplier, should
be interpreted as integer Bitcoin amounts:

   `amount`: optional number in that currency, followed by an optional
   `multiplier` letter. The unit encoded here is the 'social' convention of a
   payment unit -- in the case of Bitcoin the unit is 'bitcoin' NOT satoshis.

Vasil Dimov 158d2212c2 closingd: configurable closing fee negotiation step
When negotiating the transaction fee for closing a channel [1], we used
to always pick the middle of the range between our proposal and the
peer's proposal.

Introduce a new option `fee_negotiation_step` to the close command, so
the peer who initiates the close can choose his back off step.

Partially resolves https://github.com/ElementsProject/lightning/issues/3270

Rusty Russell 3b4a06f52b common: generalize ecdh function.
common/onion is going to need to use this for the case where it finds a blinding
seed inside the TLV.  But how it does ecdh is daemon-specific.

We already had this problem for devtools/gossipwith, which supplied a
special hsm_do_ecdh().  This just makes it more general.

So we create a generic ecdh() interface, with a specific implementation
which subdaemons and lightningd can use.
