Instead of val_to_bin/val_from_bin which deal with bytes, we implement
read and write which use streams. This simplifies the API.

This supports infrasructure for creating messages. In particular, it
can be fed CSV from the spec's `tools/extract-formats.py` and then convert
them all to and from strings and binary formats.

Changelog-Added: pyln: new module pyln.proto.message
Prior to this commit, passing a NULL stack to `bitcoin_tx_input_set_witness`
unsets the witness stack on the bitcoin_tx's wally_tx but leaves the
final witness on the PSBT unchanged.
at the moment, libwally's `wally_psbt_input_set_final_witness` will blow
up if you attempt to set a NULL witness -- instead we manually remove it
if the passed in stack is NULL. previously we would leave the PSBT's
witness unchanged.
We use a database snapshot with 3 channels -- two of which have HTLCs
dangling and one is an initial open channel tx in the 'old' tx hex
format in last_tx and confirm that they are successfully updated to PSBT
format on start.
We update the `last_tx` in `channels` to be psbt format, instead
of a linearized transaction.
We need the amount of the input populated, which we have since
this is the 'funding' amount. Ideally we'd also populate the funding
scriptPubkey, but to do that we'd need to access the HSM module to fetch
our local funding pubkey, which isn't initialized at the time that the
database migrations are run.
Since the only field the HSM uses currently when signing these is the
amount field, it's ok to just leave it out.
needs a test!
We're going to use the hsm for a migration, so we need to set up the HSM
before we get to the wallet migration code.
All that this requires is removing the places in HSM init that we touch
the database struct -- easy enough to accomplish by passing the required
field back out from init, and then associating it onto the wallet after
it's been initialized.
calling `wally_psbt_finalize` doesn't return a status indicator; instead
you must call `psbt_is_finalized` to check that it's eligible for
'extraction' -- extraction will fail if the psbt is not in a finalized
state.
when re-populating a channel's data from the database, since we don't
store the psbt data (with input scripts + amounts), we need to
re-populate it.
the right solution is to patch the psbt into the database; for now we
'monkey-patch' it in.
Update the `bitcoin_tx_add_input` interface to accept a witness script
and or scriptPubkey.
We save the amount + witness script + witness program (if known) to
the PSBT object for a transaction when creating an input.
the PPA is no longer maintained, the new hotness is the snapd install.
except that snapd does some weirdness with the binary names, calling it
bitcoin-core.daemon and bitcoin-core.cli. To get around this, you can
create a symbolic link to the snap binaries, which is what we outline
here.
According to #3226, it looks like clang's LD error format has changed.
This patch adds the new format so we can parse the mocks successfully.

Changelog-Fixed: Build for macOS Catalina / Apple clang v11.0.3 fixed
Spec is wrong (it says it should be compulsory), and Eclair doesn't set it
at all, leading to an error when they send their announcement_signatures.
Fixes: #3703
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-changed: large-channels: negotiate successfully with Eclair nodes.
There are various places where our tests failed with
--enable-expimental-features. And our plugin test overlapped an
existing feature.
We make our expected_feature functions more generic, and use them
everywhere.

For the moment it's a complete tx, but in future designs we might only
be given the specific input which closes the channel.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Otherwise this creates noise for the next patch which switches the initial
`struct bitcoin_tx` into a `struct tx_parts`.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
`struct tx_parts` is just a txid and a bunch of inputs and outputs,
some of which may be NULL.
This is both a nod towards a future where we (or our peer) can combine
HTLCs or (in an eltoo world) commitments, although for the moment all
our tx_parts will be complete.
It also matches our plan to split `bitcoin_tx` into two types: this
`struct tx_parts` where we don't know input amounts etc, and `psbt`
where we do.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
These are useful for tx_parts:
1. wally_txid.
2. linearize_wtx.
3. wally_tx_input_spends
4. wally_tx_output_get_amount
5. wally_tx_input_get_txid
