Rusty Russell 12f298d830 openingd: tell lightningd what channel type we negotiated.
Currently we actually insist it's the default, but in future it could be
different.

We also need to tell openingd what the channel_type was, if we resume
via openingd_funder_complete().

Rusty Russell d12a2ec76a openingd: don't hand redundant feature flags.
Openingd can query them itself (as dualopend already does).  And move
the two feature args next to each other on the wire.

Rusty Russell 1752616386 closingd: allow higher closing fee if anchor_outputs.
This follows https://github.com/lightningnetwork/lightning-rfc/pull/847.

For anchor_outputs, we pass down a max_feerate to closingd, and set the
fee ceiling to MAX.  It uses that to estimate the desired closing fee.

Rusty Russell 79d7e83f51 --experimental-quick-close to enable quick-close negotiation
Based on a commit by @niftynei, but:
- Separated quickclose logic from main loop.
- I made it indep of anchor_outputs, use and option instead.
- Disable if they've specified how to negotiate.

It also gets rid of the requirement that close negotiation fee maximum

This includes the new bolt11 test vectors, and also removes the

Rusty Russell fe86c117d9 datastore: turn keys into arrays
After some discussion with @shesek, and my own usage, we agreed that
a more comprehensive interface, which explicitly supports grouping,
is desirable.

Thus keys are now arrays, with the semantic that a key is either a
parent or has a value, never both.

For convenience in the JSON schema, we always return them as arrays,
though we accept simple strings as arguments.

Michael Schmoock 24ea498350 cleanup: rename use_proxy_always to always_use_proxy to match cfg
This renames all occurences of use_proxy_always to always_use_proxy
to keep it inline with config values. This was a bit confusing.

Only significant change is that the payload in the plugins init
requests also contained the old name. No plugin currently seems to make
use of this variable yet. The old name 'use_proxy_always' is added when
deprecated APIs is enabled.
