Technically an API break, but nobody relies on these I hope!
Note that the feerates warning was buried inside the style object:
it should be top-level.

This commit collects the changes required to the tests caused by the changes
to the `pay` and `paystatus` commands. They are also rather good hints as to
what these changes entail.
These are pulled from wallet/wallet.c, with the fix now that we grind sigs.
This reduces the fees we pay slightly, as you can see in the coinmoves changes.
I now print out all the coin moves in suitable format before we match:
you only see this if the test fails, but it's really helpful.

By setting nLocktime to the current block, the reorg test
"test_funding_reorg_remote_lags" actually drops the funding transaction
entirely when a reorg happens.
Except the 1 in 10 cases where nLocktime is randomly set to 1-10
blocks earlier.
This implies, strongly, that we hit "restart" too often on Travis.

There are various places where our tests failed with
--enable-expimental-features. And our plugin test overlapped an
existing feature.
We make our expected_feature functions more generic, and use them
everywhere.

Much nicer for grepping, since `{ "foo": { "bar": [7] } }` is turned into
`foo.bar[0]=7`.
Changelog-Added: cli: New `--flat` mode for easy grepping.

-H removes the top-level if there's only one, and 'format-hint'
breaks this heuristic, so we end up with:
```
help=command=autocleaninvoice [cycle_seconds] [expired_by]
category=plugin
description=Set up autoclean of expired invoices.
verbose=Perform cleanup every {cycle_seconds} (default 3600), or disable autoclean if 0. Clean up expired invoices that have expired for {expired_by} seconds (default 86400).
command=check command_to_check

This moves the notification for our coin spends from when it's
successfully submited to the mempool to when they're confirmed in a
block.
We also add an 'informational' notice tagged as `spend_track` which
can be used to track which transaction a wallet output was spent in.
A CONSERVATIVE/3 target for them.
Some noisy changes to the tests as we had to update the estimatesmartfee
mock.
Changelog-Changed: We now use a higher feerate for resolving onchain HTLCs and for penalty transactions
This is to prepare for dynamic features, including making plugins first
class citizens at setting them.

This adapts our fee estimations requests to the Bitcoin backend to the
new semantic, and batch the requests.
This makes our request for fees much simpler, and leaves some more
flexibility for a plugin to do something smart (it could still lie before
but now it's explicit, at least.) as we don't explicitly request
estimation for a specific mode and a target.
Changelog-Changed: We now batch the requests for fee estimation to our Bitcoin backend.
Changelog-Changed: We now get more fine-grained fee estimation from our Bitcoin backend.
We kept track of an URGENT, a NORMAL, and a SLOW feerate. They were used
for opening (NORMAL), mutual (NORMAL), UNILATERAL (URGENT) transactions
as well as minimum and maximum estimations, and onchain resolution.
We now keep track of more fine-grained feerates:
- `opening` used for funding and also misc transactions
- `mutual_close` used for the mutual close transaction
- `unilateral_close` used for unilateral close (commitment transactions)
- `delayed_to_us` used for resolving our output from our unilateral close
- `htlc_resolution` used for resolving onchain HTLCs
- `penalty` used for resolving revoked transactions
We don't modify our requests to our Bitcoin backend, as the next commit
will batch them !
Changelog-deprecated: The "urgent", "slow", and "normal" field of the `feerates` command are now deprecated.
Changelog-added: The fields "opening", "mutual_close", "unilateral_close", "delayed_to_us", "htlc_resolution" and "penalty" have been added to the `feerates` command.
ChangeLog-Added: New `getsharedsecret` command, which lets you compute a shared secret with this node knowing only a public point. This implements the BOLT standard of hashing the ECDH point, and is incompatible with ECIES.
Instead of saving a stripped_update, we use the new
local_fail_in_htlc_needs_update.
One minor change: we return the more correct
towire_temporary_channel_failure when the node is still syncing.

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.
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.
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.
Some Linux OSs impose a length limit on the path a Unix socket may have. This
is not an issue in `lightningd` since we `chdir()` into that directory before
opening the socket, however in pyln this became a problem for some tests,
since we use absolute paths in the testing framework. It's also a rather
strange quirk to expose to users.
This patch introduces a `UnixSocket` abstraction that attempts to work around
these limitations by aliasing the directory containing the socket into
`/proc/self/fd` and then connecting using that alias.
It was inspired by Open vSwitch code here https://github.com/openvswitch/ovs/blob/master/python/ovs/socket_util.py

Thanks to @t-bast, who made this possible by interop testing with Eclair!
Changelog-Added: Protocol: can now send and receive TLV-style onion messages.
Changelog-Added: Protocol: can now send and receive BOLT11 payment_secrets.

addresses issue #2753.
Formatting the JSON with the default parameters will escape the unicode
symbols in a way that c-lightning won't allow, leading to an exception.
Changelog-Fixed: `pylightning` now handles unicode characters in JSON-RPC requests and responses correctly.
This will change the command `listconfigs` output in several ways:
- Deprecated the duplicated "plugin" JSON output by replacing it with
- a "plugins" array with substructures for each plugin with:
- path, name and their options
Changelog-Changed: JSON-RPC: `listconfigs` now structures plugins and include their options
Changelog-Deprecated: JSON-RPC: `listconfigs` duplicated "plugin" paths
Do the same thing '--help' does with them; append `...`.
Valgrind noticed that we weren't NUL-terminarting if answer was over
78 characters.
Changelog-Fixed: JSONRPC: listconfigs appends '...' to truncated config options.
