The previous implementation was a bit lazy: in particular, since we didn't
remember the disabled plugins, we would load them on rescan.
Changelog-Changed: config: the `plugin-disable` option works even if specified before the plugin is found.
That's more convenient for most callers, which don't need a fmt.

This is what I expected from plugin_kill, and now all the callers do the
equivalent anywat, it's easy.

This means we now clean up options in startup plugins (that was only
done by dynamic code!), and now they both share the 60 second timeout
instead of 20 seconds for dynamic.
For the dynamic case though, it's 60 seconds to both complete
getmanifest and init, which seems fair.

We modify the slow_init() so it doesn't go too slowly for this test.
This demonstrates a crash, where we currently try to fail a command
multiple times.

This actually passes fine, but it's an interesting case to test.

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.
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.
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.
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.

We weren't actually waiting until l3 got the channel_update from l2,
so it might not be able to create the routehint.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
When route returns a result which is too expensive, we try to figure out which
hop is most expensive to exclude it for next time.
If it's a single-hop route, we don't count it, since the first hop is free.
That's not usually a problem, since single-hop routes can't exceed our limits
(they're always "free"!).
But if we are using a routehint, the total cost could exceed our limits,
even if the start of the routehint is a single hop away.
This reproduces that test case.

This makes testing easier, and makes sense: lightningd might not
*know* about other connected channels, depending on gossip, but if the
user specifies it we should obey it.

Changelog-Changed: JSON: `invoice` `exposeprivatechannels` now includes explicitly named channels even if they seem like dead-ends.
This is what actually lets us pay blinded invoices.
Unfortunately, our internal logic assumes every hop in a path has a
next `short_channel_id`, so we have to use a dummy. This is
sufficient for testing, however.

Sending update_fee immediately after channel establishment seems to
upset LND, so work around it by deferring it. The reason we increase
the fee after establishment is because now we might need to close the
channel in a hurry due to htlcs, but until there are htlcs that's
unnecessary.
Fixes: #3596
Changelog-Changed: Added workaround for lnd rejecting our commitment_signed when we send an update_fee after channel confirmed.

We now track all pending RPC passthrough calls, and terminate them with an
error if the plugin dies.
Changelog-Fixed: JSON-RPC: Pending RPC method calls are now terminated if the handling plugin exits prematurely.
The spec states that invoices with an amount, but lacking a multiplier, should
be interpreted as integer Bitcoin amounts:
`amount`: optional number in that currency, followed by an optional
`multiplier` letter. The unit encoded here is the 'social' convention of a
payment unit -- in the case of Bitcoin the unit is 'bitcoin' NOT satoshis.
Suggested-by: Stefano Pellegrini <@St333p>
Signed-off-by: Christian Decker <@cdecker>
Changelog-Fixed: invoice: The invoice parser assumed that an amount without a multiplier was denominated in msatoshi instead of bitcoins.
We had them split according the separate use-cases:
- testing
- doc-gen
- wire-gen
But that was causing new contributors to miss some dependencies when they
first got hacking. So this consolidates all of our own dependencies in a root
requirements.txt, with the notable exception of `pyln-client`, `pyln-testing`
and `pyln-proto` which are distributed as PyPI modules and therefore have
their own dependencies that need to be tracked in the module root.
Closes#3518
Note that now we check capacity once we've figured out which peer, which
broke a test (we returned "unknown peer" instead of "capacity exceeded"),
so we rework that too.
