libwally has a bug which results in it failing to parse the 'empty tx'
cHNidP8BAAoAAAAAAAAAAAAAAA==. While we wait for the patch to land in
libwally, we patch over it.
Fix at: https://github.com/ElementsProject/libwally-core/pull/273
If we only add a single input/output for the funding transaction,
we'll only call openchannel_update once, which results in
a crash because the dest->state will never advance to
MULTIFUNDCHANNEL_UPDATED;
Instead, we update to UPDATED before we check for doneness.
We generally hang things off our JSON response (this pattern predates
tmpctx!) but sometimes it gets reported as a memleak. I'd prefer not
to mark JSON responses as "notleak", since they can be allocated for
a while), so use tmpctx here.
```

We didn't wait for the sendtx to complete before shutting down,
and hence timed out:
```
l2.daemon.wait_for_log('Broadcasting funding tx')
l1.stop()
l2.stop()
bitcoind.generate_block(6)
l1.restart()
l2.restart()
# Make sure we're ok.
> l2.daemon.wait_for_log(r'to CHANNELD_NORMAL')

e.g. in test_closing_id we can get a spend from the first (closed) channel
in the same block as the open of the second. Half the time, we'll choose
the wrong one as scid.

Channel can be inactive before it disconnects, apparently. Check
explicitly for the disconnected state so we get the expected error.
Here's what happened:
```
# Can't pay while its offline.
with pytest.raises(RpcError, match=r'failed: WIRE_TEMPORARY_CHANNEL_FAILURE \(First peer not ready\)'):
> l1.rpc.sendpay(route, rhash)
E Failed: DID NOT RAISE <class 'pyln.client.lightning.RpcError'>
```
And the logs show that the outgoing HTLC was sent to channeld before it
realized the connection was closed.

Change the address in the canned db: it seems we won the lottery and
l1 connected, and got an error!

Add an extra run configuration for the proto-tests.
Proto-tests require DEVELOPER=1; enabling EXPERIMENTAL_FEATURES=1
by default ensures that experimental additions are automatically put
under test also.
This centralizes the setup.py file, and parametrizes it so it can
auto-detect which bolt we are building. It also uses trick 3 from [1]
to avoid importing the package itself during the manifest creation,
which'd cause an import error due to missing dependencies.
[1] https://packaging.python.org/guides/single-sourcing-package-version/
This would lead to errors about missing dependencies when attempting
to install using `pyhon setup.py install`. This is because the
`setup.py` file effectively is the manifest file used to discover
which dependencies are needed, so when using it to detect dependencies
we obviously don't have them yet.
See https://packaging.python.org/guides/single-sourcing-package-version/
They are currently not installable due to circular dependencies and
stuff, so we just add their source to the path and lnprototest will
pick them up from there.
This allows to not have to worry about the source of the installation,
and we always use our in-tree version. It also means we pull in the
requirements.txt files through the setup.py and don't need to
replicate them.
Instead of "only check suffix quotes when EXPERIMENTAL_FEATURES", make
it so we only check suffix quotes if you override BOLTVERSION on the
cmdline.
Before this, "make check-source-bolt" was effectively a NOOP with
--enable-experimental-features.

The main change which affects us is that 2016 blocks to forget a channel
is a fixed number in the spec; we make this clear by renaming the
(developer-only) max_funding_unconfirmed to dev_max_funding_unconfirmed
and making it compile DEVELOPER only.

They're not defined to be, though we've not seen this on Linux (testing
showed that it is page-level atomic, which means it can still happen across
page boundaries though!). This was pointed out by whitslack in
https://github.com/ElementsProject/lightning/issues/4288
In practice, this just means not complaining when it happens, and also
not trying to get tricky to use it on MacOS (we can safely seek & write,
since we're single-threaded).

Changelog-Removed: Removed bogus UNUSUAL log about gossip_store 'short test'.
We weren't writing out the length of a nested subtype's
dynamicarraylenght, now we do. The trick is to iterate through the
fields on a subtype (since the length field is added separately)
and to also iterate down through the otherfield values as we 'descend'
It's unlikely but possible that a race condition will result in us not
being at the 'secured' state yet here.
Crashlogs. All required msgs are received (in order)
from peers, but the crash suggests they weren't relayed/processed by the
spender plugin in the order received.
WIRE_TX_SIGNATURES is passed the the plugin via a notification;
WIRE_COMMITMENT_SIGNED is returned as the result of an RPC call.
