niftynei 4034d0c306 psbt: have the unknown map 'add' be a 'set' instead 2020-10-20 14:27:19 +10:30
niftynei 085c590a51 dualopen: use separate wire for passing updated PSBTs back to dualopend
Rusty pointed out that having an empty channel_id is suboptimal; adding
another call is probably the right idea rather than re-using an existing
one.

niftynei 41ebf71e26 psbt: new methods for generating serial_ids for an input/output

niftynei 3a405c33e6 dualfund: Pass in expected remote's serial parity
Now that we've got the opener in progress, we need to be able to toggle
which parity to check a remote's serial_ids for

niftynei 06c41a0547 dualfund: opener, openchannel_init command (1/3)
There are 3 commands for opening a channel with dualfunding.
`openchannel_init` is the first of these.

It initializes the open-channel dialog, and stops once we've run out of
updates (input/outputs) to send to the peer.

niftynei 2618ef10c3 tx_roles: pull up roles, rename
We're going to use these elsewhere/more widely so having them in common
and using a more generic name is a obvious place to start.

Rusty Russell f37f2b6193 common/memleak: simplify and document API.
1. Rename memleak_enter_allocations to memleak_find_allocations.
2. Unify scanning for pointers into memleak_remove_region / memleak_remove_pointer.
3. Document the functions.

Rusty Russell 3c8049f32c bitcoin/psbt: psbt_input_add_unknown/psbt_output_add_unknown needs a tal ctx.
Since it allocates something, it needs a context (used in the next patch!).

Rusty Russell 480f671e91 bitcoin/psbt: psbt_txid needs a tal ctx.
It returns a wally_tx; it's an anti-pattern not to hand in a tal context.

Antoine Poinsot 4b4fe2f4fb dual-openingd: msg_type should be dualopend_wire not u8
clang did the hard work here:

openingd/dualopend.c:958:42: error: result of comparison of constant 'WIRE_DUAL_OPEN_FAIL' (7003) with expression of type 'u8' (aka 'unsigned char') is always false
      [-Werror,-Wtautological-constant-out-of-range-compare]

niftynei b44e36b99e spec-update: get rid of max-witness-len
We can use a fixed value and close the channel if they don't cover their
amount; this wasn't really helping with anything other than setting a
floor for an expected feerate

niftynei c50f377a85 psbt: pull out changeset logic into common, update API
Greatly simplify the changeset API. Instead of 'diff' we simply generate
the changes.

Also pulls up the 'next message' method, as at some point the
interactive tx protocol will be used for other things as well
(splices/closes etc)
