LightningNode.join_nodes and LightningNode.openchannel internally
generate blocks, which causes nodes to be out of sync, and ignore
"future" announcements, because they haven't seen that block yet.
It was using a trick to only shut down the first node, and forgetting
about the others. This could lead to processes not being stopped
correctly and to test failures because the directory isn't cleaned up
correctly.
Now we use the executor to shut as many nodes as possible in parallel.
In the case where you want a PSBT and also want the output to be added
as a change address, use `excess_as_change` = true.
Generates a change address to use. If you want to pay the excess
elsewhere, you will have to add separately.
Changelog-Added: JSON-RPC: Add new parameter `excess_as_change` to fundpsbt+utxopsbt
Since we turned many errors into warnings, we want our tests to fail
when they happen unexpectedly. We make WARNING clear in the strings
we print, too, to help out.

No more sending "all-channel" errors; in particular, gossipd now only
sends warnings (which make us hang up), not errors, and peer_connected
rejections are warnings (and disconnect), not errors.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: Plugins: `peer_connected` rejections now send a warning, not an error, to the peer.
And make all the callers choose which one. In general, I prefer warn,
which lets them reconnect and try again, however some places are either
stated that they must be errors in the spec itself, or in openingd
where we abandon the channel when we close the connection anyway.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: Protocol: we now send warning messages and close the connection, except on unrecoverable errors.
We construct the route manually so we may not have the
channel_announcement yet. But we can get an update from the error
packet, which can lead to:

We should actually be including this (as it may define _GNU_SOURCE
etc) before any system headers. But where we include <assert.h> we
often didn't, because check-includes would complain that the headers
included it too.
Weaken that check, and include config.h in C files before assert.h.

We fix up the test by using pay, instead of sendpay (and making pay log
the expected message).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: sendpay no longer extracts updates from errors, the caller should do it from the `raw_message`.
Nit: The underscore in "openchannel_hook" is wrong, bcause the name of
the hook is just "openchannel". The "_hook" implied this to be part of
the name.
Changelog-None
The test was not considering that concurrent sendrawtx of the same tx
is not stable, and either endpoint will submit it first. Now just
checking state transitions and the mempool.
If we're quick (or the node is slow) we end up reconnecting before our
counterparty has realized the state transition, resulting in an
unexpected re-establish.
We were sometimes waiting only 5 seconds, which is way too short on a
heavily loaded machine such as CI. Making it 30 seconds and collecting
it in a single place so we can adjust more easily.
We also make the logic a bit nicer to read. The failure was due to
more than one status message being present if we look at the wrong
time:
```
arr = ['CLOSINGD_SIGEXCHANGE:We agreed on a closing fee of 20334 satoshi for tx:17f1e9d377840edf79d8b6f1ed0faba59bb307463461...9b98', 'CLOSINGD_SIGEXCHANGE:Waiting for another closing fee offer: ours was 20334 satoshi, theirs was 20332 satoshi,'] │
def only_one(arr):
"""Many JSON RPC calls return an array; often we only expect a single entry
"""
> assert len(arr) == 1
E AssertionError
```
We weren't waiting for the transactions to enter the mempool which
could cause all of our fine-tuned block counts to be off. Now just
waiting for the expected number of txs.

Changelog-Added: plugins: plugins can now disable themselves by returning `disable`, even if marked important.
Note that this also changes so the feature is not represented in channels,
reflecting the recent drafts.
