We use parameterization here. The old `anchor_expected()` was for
non-zero-fee anchors, and have bitrotted so there are some other
changes as well.
Unfortunately, all the anchor accounting seems to be broken, but I
cannot understand these tests at all. I had to simply disable them
for now.

We disabled experimental support for opening non-zero-fee anchor
channels (though old nodes may still have such channels if they turned
that on!).
So we simply call this `experimental-anchors`, since this is the variant
which we expect to be used widely.

Changelog-EXPERIMENTAL: protocol: added support for zero-fee-htlc anchors (`option_anchors_zero_fee_htlc_tx`), using `--experimental-anchors`.
In most cases, it's the same as option_anchor_outputs, but for
fees it's different. This transformation is the simplest:
pass it as a pair, and test it explicitly.
In future we could rationalize some paths, but this was nice
and mechanical.

Since HTLC txs when using anchors are
SIGHASH_SINGLE|SIGHASH_ANYONECANPAY, we can attach other inputs to
give it a higher feerate. But we need the HSMd to actually sign the
combo.

We need to know both, because in theory we could negotiate a
non-anchor channel even if they support it.

Since we can CPFP, we don't have to track the feerate as closely. But
it still needs to get in the mempool, so we use 10 sat/byte, or the
100 block estimate if that is higher.

Changelog-Added: JSON-RPC: `feerates` has new fields `unilateral_anchor_close` to show the feerate used for anchor channels (currently experimental), and `unilateral_close_nonanchor_satoshis`.
Changelog-Changed: JSON-RPC: `feerates` `unilateral_close_satoshis` now assumes anchor channels if enabled (currently experimental).
mfc->feerate_str is *never* NULL, since we set it in getfeerate; this is
confusing, as many places check for NULL.
Indeed, the logic in perform_fundpsbt() was *wrong* in this case: it used
`normal` (if it was NULL, which it never was) instead of `opening` to fundpsbt.
And the correct thing is for multifundchannel to not use a string here at
all, but to use the exact feerate it is counting on (even the same
string may have different values now if a block has come in).

We don't actually use it anywhere, but we actually want to now for
CPFP. So give it more parameters and make it return bool so it can
be set without necessarily suppressing rexmit.

Turns out it's a single sig, identical to the already-handled
case where we spend a to_remote output.
We also close a temporary memleak: stack was unused, but
tallocated off the psbt, so it lives as long as the PSBT.

It depends on whether we negotiated anchors: just document that this
field doesn't apply for anchors (it becomes zero by the end of this
patch series, which is weird).

We were setting the wrong input number: don't assume it's the
same as the UTXO number, but simply the last-appended input.

It'll wrap, probably be in the past, and infinite loop. This was caused by an invoice
with expiry set at 2076. This wrap caused us to think the expiry has already
passed, and keep looping!

Changelog-Fixed: lightnind: don't infinite loop on 32 bit platforms if only invoices are expiring after 2038.
And add contrib/pyln-testing/pyln/testing/grpc2py.py since we didn't previously know
how to build it!

See the section headed "Rules with Grouped Targets" on the Texinfo page
`(make)Multiple Targets`.
Without this fix, Make does not know that these recipes unconditionally
make *all* of their named targets regardless of which target triggers
their execution, and Make will blissfully execute multiple instances of
any such recipe in parallel, not only wasting CPU cycles but potentially
producing incorrect results if the recipe is not atomic in its effects
on the file system. With this fix, Make understands that it need only
execute such a recipe once to make all of its targets.
In pursuit of the above, move and combine two redundant msggen recipes
into the top-level Makefile, and populate its grouped targets from the
subordinate Makefiles.
Changelog-None
Add a fuzz test for BOLT 8 message encryption and decryption. The fuzz
test is based on the unit test at common/test/run-cryptomsg.c and uses a
static initial state with fuzzer-generated messages to encrypt or
decrypt.
This header will be used by multiple fuzz targets to fuzz Acts 1, 2, and
3 of the BOLT 8 handshake.
We could make this header into a full library, but considering its
narrow use let's try not to over-engineer things.
It seems to reliably be getting a SIGTERM after 17-18 minutes:
```
[gw1] [ 91%] PASSED tests/test_plugin.py::test_forward_event_notification
Error: Process completed with exit code 143.
```
Perhaps this is out of mem? So, try -n2. We also make the configure
line explicit, rather than relying on environment vars (we should probably
do this for the other cases, too)

Since we didn't hash the descriptions properly (see previous commit), we
cannot immediately deprecate omitting the descriptions (since you'd
have to omit them for backwards compat!).
And move the "must have description or hash" test into bolt11.c core.
Changelog-Deprecated: `pay` has *undeprecated* paying a description-hash invoice without providing the description.
