We need the PSBT to create the finalized tx from once the peer's
tx_signatures are received. Since we're passing the PSBT, we no longer
need the secondary message to be passed, as it was derived from the
PSBT.
Also removes now unused witness serialization code
We need this for dual funding, since the interactive tx construction
protocol requires the full tx to send places. We add it to all PSBTs (if
we have it), here
This adds an environment variable $NO_PYTHON check to Makefiles so that:
- It checks and runs into an defined error instead of some python hickup:
`ModuleNotFoundError: No module named 'mako'`
- makes it possible to manually export this environment variable NO_PYTHON=1
to run the same testcase that travis is running on job 1 which causes
so much pain ;)
Changelog-None
I discovered this accidentally when using the `tests/plugins/dblog.py`
plugin on another testcase: tests/test_connection.py::test_fail_unconfirmed
There the plugin/hook crashes because it can't execute the statement:
```json
{
"jsonrpc": "2.0",
"id": 34,
"error": {
"code": -32600,
"message": "Error while processing db_write: unrecognized token: \"174WHERE\"",
"traceback": "Traceback (most recent call last):\n File \"/home/will/projects/lightning.git/contrib/pyln-client/pyln/client/plugin.py\", line 535, in _dispatch_request\n result = self._exec_func(method.func, request)\n File \"/home/will/projects/lightning.git/contrib/pyln-client/pyln/client/plugin.py\", line 520, in _exec_func\n return func(*ba.args, **ba.kwargs)\n File \"/home/will/projects/lightning.git/tests/plugins/dblog.py\", line 45, in db_write\n plugin.conn.execute(c)\nsqlite3.OperationalError: unrecognized token: \"174WHERE\"\n"
}
}
```
Changelog-Fixed: plugin: Regression with SQL statement expansion that could result in invalid statements being passed to the `db_write` hook.
I got a corrupt file, which looked like multiple concurrent attempts
to build it. So instead, build it in one command, but also use
VERBOSE so we print correctly with V=1 (and --quiet).
Also move into plugins/ where it logically belongs.

We force use of tal_wally_start/tal_wally_end around every wally
allocation, and with "end" make the caller choose where to reparent
everything.
This is particularly powerful where we allocate a tx or a psbt: we
want that tx or psbt to be the parent of the other allocations, so
this way we can reparent the tx or psbt, then reparent everything
else onto it.
Implementing psbt_finalize (which uses a behavior flag antipattern)
was tricky, so I ended up splitting that into 'psbt_finalize' and
'psbt_final_tx', which I think also makes the callers clearer.

These are simple space-separated key-value pair sets of options instead of the
URI style DSNs, but they are also much more flexible allowing the user to
specify client SSL certificates, server certificates, compression and
encryption levels, and much more (see [1] for more information)

Changelog-Added: db: Added support for key-value DSNs for postgresql, allowing for a wider variety of configurations and environments.

This notification will be raised whenever a channel state changes.
The payload includes the channel and peer identifiers and the
old and the new state.
Example payload:
```
{
"channel_state_changed": {
"peer_id": "03bc9337c7a28bb784d67742ebedd30a93bacdf7e4ca16436ef3798000242b2251",
"channel_id": "a2d0851832f0e30a0cf778a826d72f077ca86b69f72677e0267f23f63a0599b4",
"short_channel_id" : "561820x1020x1",
"old_state": "CHANNELD_NORMAL",
"new_state": "AWAITING_UNILATERAL"
}
}
```
Changelog-Added: Plugins: channel_state_changed notification
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)

dual funding needs the max-witness-len and utxo fields set for every
input. we should add them when we create a 'fundpsbt', so that every
psbt that c-lightning generates is dual-funding ready
v2 of channel establishment, in the accpeter case, now sends 2 messages
to our peer after saving the information to disk (our commitment
signatures and our funding transaction signatures)
v2 channel open uses a different method to derive the channel_id, so now
we save it to the database so that we dont have to remember how to
derive it for each.
includes a migration for existing channels
fundpsbt / utxopsbt create a (typically) output-less PSBT,
however for elements we require the fees to be encapsulated in an
output.
this patch updates fundpsbt / utxopsbt to add a fee output for elements
transactions. includes test updates.
Fixes#3998
We defer the notification to gossipd till the end of the spends. By itself not
a huge change, but it allows us to later migrate to doing updates blindly and
using the DB as our ground truth. It also allows us to simplify the
`wallet_outpoint_spend` semantics to not return two values in the next commit.
We're going to want this for bolt13 formation as well.
As a result of reworking the logic into "candidate selection" then
"route hint selection", we need to change the way round-robin works.
We use a simple incrementing index now.

This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.
This changes test_withdraw, since it asserted that outputs were marked
spent as soon as we broadcast a transaction: now they're reserved until
it's mined. Similarly, test_addfunds_from_block assumed we'd see funds
as soon as we broadcast the tx.

Changelog-Changed: JSON-RPC: `withdraw` now randomizes input and output order, not BIP69.
Marking spent means if the transaction doesn't confirm for some
reason, the user will need to force a rescan to find the funds. Now
we have timed reservations, reserving for (an additional) 12 hours
should be sufficient.
We also take this opportunity (now we have our own callback path)
to record the tx in the wallet only on success.

This avoids overwriting the ones in git, and generally makes things neater.
We have convenience headers wire/peer_wire.h and wire/onion_wire.h to
avoid most #ifdefs: simply include those.

Generating these requires python tooling which may not be present, so only
clean them in maintainer mode. Also remove `wallet/statements.po` which is no
longer used or generated at all.
