niftynei 9ba2f614bb psbt-open: method to quickly check if has our input
For dual-funding's accepter plugin, we only want to send
psbts that need to be signed to `signpsbt`; this lets us quickly check
if they're "signable"

niftynei 29c3532856 mfc-psbt: mark all of our inputs as "ours", then only sign those
we only want to sign the inputs that we've reserved via utxopsbt or
fundpsbt. we mark them with a flag (reusing the now defunct max-len
flag is fine), then look for inputs with that flag to pass to signonly

niftynei 97fd18f0b5 df: incorporate a few spec changes -- serial_id is now 64-bits
And we pass 3-params for feerate so it's a 'pick a range' conversation.

niftynei 9d412718df psbt: save the index of the change on the 'parent'
Note that for removals, the index will be on the original; for
additions, the index will be on the new. Yes this is implicit.

niftynei 4508584b21 dualfund: rearrange things so that the wire-dependent calls are separate
There's a few structs/wire calls that only exist under experimental features.
These were in a common file that was shared/used a bunch of places but
this causes problems. Here we move one of the problematic methods back
into `openingd`, as it's only used locally and then isolate the
references to the `witness_stack` in a new `common/psbt_internal` file.

This lets us remove the iff EXP_FEATURES inclusion switches in most of
the Makefiles.

niftynei 9d4afd5880 psbt: hoist up `psbt_add_serials`, so we can use it elsewhere
We're going to use this in multifundchannel.

we need to do this elsewhere later, pull it out so we can use it

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!).

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 aef5a5a0e5 psbt: psbt_has_serial_id -> psbt_find_serial_id
Cleans up some awkward spots in the code, makes the footprint a bit
neater

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)

  - adding a serial_id
  - getting a serial_id
  - finding the diffset between two psbts
  - adding a max_len to a psbt input
  - getting a max_len from a psbt input
