The symptom (under heavy load and valgrind) in test_plugin_command:
lightningd: common/json_stream.c:237: json_stream_output_: Assertion `!js->reader' failed.
This is because we try to call `getmanifest` again on `pay` which has not yet
responded to init.
The minimal fix for this is to keep proper state, so we can tell the
difference between "not yet called getmanifest" and "not yet finished
init".

Telling `lightningd` to pass a `-datadir` to `bitcoin-cli` so it doesn't go
snooping where it doesn't belong (i.e., the user's home directory and config).

I noticed the following in logs for tests/test_connection.py::test_feerate_stress:
```
DEBUG 022d223620a359a47ff7f7ac447c85c46c923da53389221a0054c11c1e3ca31d59-chan#1: Failing HTLC 18446744073709551615 due to peer death

```
This is because it reports the (transient) node_failure error, because
our channel_failure message is incomplete. Fix this wart up.

If we don't wait for close tx to reach mempool, it might not get to
depth 100, and we don't get 'onchaind complete, forgetting peer'.

We didn't wait until l2 processed the final state of HTLC #2, so
it might not include it when it drops onchain, leading to us only
getting 3 (not 4) sendrawtx calls.

Previously we've used the term 'funder' to refer to the peer
paying the fees for a transaction; v2 of openchannel will make
this no longer true. Instead we rename this to 'opener', or the
peer sending the 'open_channel' message, since this will be universally
true in a dual-funding world.
We were using patch's '--silent' flag, but that broke on the busybox
implementation of `patch`, since they don't support it. Instead, we use
the universally supported "pipe to /dev/null" approach

This was breaking a couple of tests if the pyln version was not synced up with
`lightningd`, so now we just warn (these are then collected when running in
pytest and highlighted).
They were looking for specific amounts which proved to be rather flaky. Now
they look for specific outputs being available in the `listfunds` result after
everything was settled.
They are already logged both in bcli, and in lightningd.
This just adds a lot of noise to the logs. We keep successed attempts
though for the tests.

The new `keysend` plugin modifies the node features that we send to
peers. This commit breaks out the 'expected_features' we use for tests
to encompass this differentiation.
The documentation was wrong, and I copied my mistake to `libplugin` where it
was then ignored instead of ORed into the node's featurebits. This fixes both.
Commit 9aedb0c61f changed this from allocating off `c` to allocating
off NULL, knowing that it's tal_steal() in the callback. But before
that, it can be detected as a mem leak:
```
@pytest.fixture
def teardown_checks(request):
"""A simple fixture to collect errors during teardown.
We need to collect the errors and raise them as the very last step in the
fixture tree, otherwise some fixtures may not be cleaned up
correctly. Require this fixture in all other fixtures that need to either
cleanup before reporting an error or want to add an error that is to be
reported.

errors = TeardownErrors()
yield errors

We only support a very limited number of argument combinations, and apparently
sometimes we trigger a case we aren't handling. This adds a more useful error
message, including the params we didn't match.
There's a race condition with loading the submodules that's causes a
build failure on my machine, since the libwally 'includes' aren't on
disk yet when the gcc build step starts.
The peer will fail the channel on reconnect if we send an 'add' we
don't have balance for yet; we can avoid this issue by always sending
fulfills (+) before sending adds (-)
As discussed with Christian, prepending the length to the payload returned
is awkward, but it's the only way to set a legacy payload. As this will
be soon deprecated, simplify the external API.

So far we were relying on `lightningd` to create an ad-hoc invoice when
telling it to `resolve` with a given preimage. We now switch to having the
plugin create the invoice, remove the mandatory `keysend_preimage`
field (which would upset `lightningd` otherwise), and then return the modified
payload with the instructions to `continue` instead of resolving.
This ties back in with the existing payment/invoice handling code. Invoices
are created only if we don't have a label clash (unlikely since we have the
nano-time in the label), or the `payment_hash` was already used for another
invoice (at which point `lightningd` will automatically reject the payment and
we're a bit poorer for it, but meh :-)
