Changelog-Added: `close` now notifies about the feeranges each side uses.
We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds). This scheme
follows the latest draft, in which features are flagged compulsory.
We also add several helper functions.
Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.

Changelog-Added: JSONRPC: `close` now takes a `feerange` parameter to set min/max fee rates for mutual close.
This is now allowed for anchors (as per https://github.com/lightningnetwork/lightning-rfc/pull/847).
We need to play with feerates, since we don't put a discount on anchor
commitments yet.

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.

This includes the new bolt11 test vectors, and also removes the
requirement that HTLCs be less than 2^32 msat. We keep that for now
because Electrum enforced it on receive: in two releases we will stop
that too.
So no longer warn about needing mpp in that case either.

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.

We add a generation counter, and allow update or del conditional
on a given generation.
Formalizes error codes, too, since we have more now.

The function is already provided in
contrib/pyln-testing/pyln/testing/utils.py (which is also
imported in this module), so there is no need to define it
a second time.
We actually were waiting for l3 to disconnect, not l2.
But in general we should be looking for status rather than grovelling
in the logs where possible, so I changed all those.
```

We fail waiting for 'Resolved OUR_UNILATERAL/DELAYED_OUTPUT_TO_US by our proposal OUR_DELAYED_RETURN_TO_WALLET'
because we close *two* channels, but only wait for one transaction before mining a block.
This means we might only have one, and we immediately mine the next wait_for_mempool=1,
so the OUR_DELAYED_RETURN_TO_WALLET isn't mined.

If l3 is too slow, it can get channel_announcement after channel
is closed, so it gets upset at the node_announcement which follows:

Pointed out by @fiatjaf, and indeed it happened to me as well; a peer with
a high feerate reconnects and sends a similar (but now ludicrous) feerate,
and we get upset:
```

As requested by @shesek: it's weird to fail if they ask for the exact
same thing (which is quite possible, since offers don't expire by

Documentation for the funderupdate command on the funder plugin.
Realized we were missing the "leases_only" in the output; also adds
'_msat' to msat denominated outputs so they're parsed correctly by our
python bindings (also matches our naming conventions)
Changelog-EXPERIMENTAL: funder: `funderupdate` command to view and update params for contributing our wallet funds to v2 channel openings. Provides params for enabling `option_will_fund`.
Since we now use 'compact_lease' to gate an open (if the rates have
changed, we fail), we no longer need to rely on query rates for figuring
things out, so we make it dev-only.
Changelog-Changed: JSON-API: queryrates is now developer only
If there's no plugin currently in place, we simply won't return any
funding at all, in which case we'd expect them to handle however
they want. (our implementation would fail the open, as we only accept
opens that have at least as much as we've requested provided)
Useful for parsing a passed in feerate before calling lightningd with
it, e.g. when you need to know what the feerate is for a fundpsbt before
calling fundpsbt
Changelog-Added: JSON-RPC: new command `parsefeerate` which takes a feerate string and returns the calculated perkw/perkb
