Changelog-Changed: The hooks `db_write`, `invoice_payment`, and `rpc_command` now accept `{ "result": "continue" }` to mean "do default action", in addition to `true` (`db_write`), `{}` (`invoice_payment`), and `{"continue": true}` (`rpc_command`). The older "default" indicators are now deprecated and are now recognized only if `--deprecated-apis` is set.
Also pulls in a new onion error (mpp_timeout). We change our
route_step_decode_end() to always return the total_msat and optional
secret.
We check total_amount (to prohibit mpp), but we do nothing with
secret for now other than hand it to the htlc_accepted hook.

Changelog-changed: .lightningd plugins and files moved into <network>/ subdir
Changelog-changed: WARNING: If you don't have a config file, you now may need to specify the network to lightning-cli

Rounds out the application of `upfront_shutdown_script`, allowing
an accepting node to specify a close_to address.
Prior to this, only the opening node could specify one.
Changelog-Added: Plugins: Allow the 'accepter' to specify an upfront_shutdown_script for a channel via a `close_to` field in the openchannel hook result

Changelog-changed: JSON API: `htlc_accepted` hook has `type` (currently `legacy` or `tlv`) and other fields directly inside `onion`.
Changelog-deprecated: JSON API: `htlc_accepted` hook `per_hop_v0` object deprecated, as is `short_channel_id` for the final hop.
This is mainly an internal-only change, especially since we don't
offer any globalfeatures.
However, LND (as of next release) will offer global features, and also
expect option_static_remotekey to be a *global* feature. So we send
our (merged) feature bitset as both global and local in init, and fold
those bitsets together when we get an init msg.

This is easy since we did the option parsing cleanup, but it has the
effect that plugins are launched from the lightning-dir. Now
we have dynamic plugins, this means startup and post-startup plugins
experience the same environment.
This is absolutely a desirable thing: they can just drop files in
their cwd rather than having to move (including, I might note, core
files!).
We also highlight the change in various places (and a drive-up update
of PLUGINS.md which says you have to use --plugin).
The next patch adds a backwards compatibility wedge for old users of
relative plugin paths.

This was deeply surprising to me; there's a difference between a value not being
specified, and it being specified as "".

This also allows plugins to do "hold invoices" a-la LND, useful for
just-in-time inventory handling.
We're careful to handle the invoice getting paid behind our backs, and
the incoming HTLC going away.
Once @cdecker's sphinx rework is in, we can also hand the raw payload
to the invoice_payment_hook, for special effects.

In theory we could allow a db_write-using plugin to have other
hooks/commands by embargoing their other responses until the exclusive
period is over. That would be nice for a 'dbmirrorinfo' command, for
example.
The other option would be to *always* go exclusive on a db_write-using
plugin, so responses can never get intermingled.
