For bitcoind_fail_first:
We only ever send `getblock` if we got a successful block hash from
`getblockhash`, and if we can't get the block in that case it means
our Bitcoin backend is faulty and we shouldnt continue.
So, mock `getblockhash` instead, which is authorized to spuriously fail.
For both bitcoind_fail_first and bitcoind_failure:
Adapt the logs.
Add new check if we're funder trying to add HTLC, keeping us
with enough extra funds to pay for another HTLC the peer might add.
We also need to adjust the spendable_msat calculation, and update
various tests which try to unbalance channels. We eliminate
the now-redundant test_channel_drainage entirely.
Changelog-Fixed: Corner case where channel could become unusable (https://github.com/lightningnetwork/lightning-rfc/issues/728)

Make the `htlc_accepted` hook the first chained hook in our repertoire. The
plugins are called one after the other in order until we have no more plugins
or the HTLC was handled by one of the plugins. If no plugins handles the HTLC
we continue to handle it internally like always.
Handling in this case means the plugin returns either `{"result": "resolve",
...}` or `{"result": "fail", ...}`.
Changelog-Changed: plugin: Multiple plugins can now register for the htlc_accepted hook.
This is the last venue we need to add custom featurebits to, so we also unmark
the test as xfail.
Changelog-Added: plugin: Plugins can now signal support for experimental protocol extensions by registering featurebits for `node_announcement`s, the connection handshake, and for invoices. For now this is limited to non-dynamic plugins only
restrict fundchannel_cancel usage to only the opener side
Changelog-Changed: Only the opener of a fundchannel can cancel the channel open with fundchannel_cancel
As a separated commit because it was pre-existent (changelog + xfail test).
This also fix a logical problem in lightningd/plugin_control: we were
assuming a plugin started with 'plugin start' but which did not comport
a 'dynamic' entry in its manifest to be dynamic, though it should have
been treated as static.
Changelog-fixed: plugins: Dynamic C plugins can now be managed when lightningd is up
Using it with a different value to the amount sent causes a crash in 0.8.0,
which is effectively deprecating it, so let's disallow it now.
Changelog-Changed: If the optional `msatoshi` param to sendpay for non-MPP is set, it must be the exact amount sent to the final recipient.

1. We asserted that there wouldn't be a raw failcode.
2. We didn't pass the failure information via JSON in this case.

We could use sendonion to do this, but it actually takes a different path through
pay, and I wanted to test all of it, so I made a new dev flag.
We currently get upset with the response:
lightningd/pay.c:556: payment_failed: Assertion `!hout->failcode' failed.

This completes the custommsg epic, finally we are back where we began all that
time ago (about 4 hours really...): in a plugin that implements some custom
logic.
This solves a couple of issues with the need to synchronously drop the
connection in case we were required to understand what the peer was talking
about while still allowing users to experiment, just not kill connections.
The number of outputs got updated, but the map used to calculate the
change output's location did not (still assumes only one output). This
patch fixes this to make the output map a variable size.
Changelog-Fixed: JSON API: `txprepare` no longer crashes when more than two outputs are specified
Changelog-Fixed: Detect a previously non-permanent error (`final_cltv_too_soon`) that has been merged into a permanent error (`incorrect_or_unknown_payment_details`), and retry that failure case in `pay`.
This is needed to fully implement handling of blockheight disagreements
between us and payee.
If payee believes the blockheight is higher than ours, then `pay`
should wait for our node to achieve that blockheight.
Changelog-Add: Implement `waitblockheight` to wait for a specific blockheight.
Changelog-Changed: plugin: `notify_sendpay_success` and `notify_sendpay_failure` are now always called, even if there is no command waiting on the result.
We clone the test above, but this time we don't attach waiters (they'd be racy
anyway), and we wait for the notification to be called. This fails, but is
fixed in the next two commits.
Valgrind doesn't really like crashes if compiled without DEVELOPER since that
seems to compile out the debug symbols, resulting in the following error:
```
Optimistic lock on the database failed. There may be a concurrent access to the database. Aborting since concurrent access is unsafe.
