Rusty Russell 44c469d52b disableoffer: fix disabling of already-used offers.
Turns out we didn't actually test this at all, and next commit does :(

Rusty Russell 57cc4e3c34 fetchinvoice: don't consider "msat" a change if fetchinvoice specified it.
We don't automatically *reject* an invoice which asks for a different
msat than we specified (caller may!), but we don't bother noting it
unless it is different.

Rusty Russell 0a0b2ce940 offers: make sure quantity limits are sane.
You could have quantity_min of 0, which makes no sense; spec has been
updated, so quote and enforce that.

Rusty Russell 7769903f1a bolt12: import latest spec (timestamp -> created_at).
@shesek points out that we called this field created_at in bolt11 decode,
which makes more sense anyway.

Changelog-EXPERIMENTAL: bolt12 decode `timestamp` field deprecated in favor of new name `created_at`.

niftynei 90c5f9a051 funderupdate: add documentation, update some params
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`.

niftynei 77d2c538b3 queryrates: make it dev-only
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

niftynei b067820dd8 lease-channels: tests for the test gods
Check that channel leases work as expected for unilateral closes
and cheats!

niftynei a8ee69cdc8 dualopend: hold onto open_tlv for longer than the tmpctx persists
with channel leases, we use the open_tlv data after a round of talking
to the peer (which clears out the tmpctx). It'll get cleaned up
when this peer opens/fails.

niftynei d4408a9ae0 channel-leases: add lease fee to accepter's funding earlier up
We need the 'actual' accepter's funding for the reserve calculations,
which includes the lease fee that the opener is paying them, so we
calculate it before doing all that jazz.

However, we MUST send the actual "on paper" (e.g. without lease fee)
amount to the peer in accept_channel2, so we stash the original amount
and send it.

niftynei 70bf57d54b channel-lease: reject if we're not currently advertising liquidity
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)

niftynei d05a2a5aa9 channel leases: add expected lease fee to opening PSBT
We need to parse the feerate string, so we can figure out what our
weight fee will be for a leased channel, so we go get the feerate
and use that to calculate what our expected lease fee will be for
the requested amount.

niftynei f24bbac8d9 channel leases: pass expected lease rates around in compat form
We need to know what the lease we're expecting is. To do this
we pass around the hex encoded portion of the wire format.

We can use this passed in expected lease rates to confirm that the peer
is, in fact, using the same rates as what we have currently.

Changelog-Added: JSON-RPC: fundchannel, multifundchannel, and openchannel_init now accept a 'compact_lease' for any requested funds

niftynei f3b54a510b close: param to force-close a leased channel

niftynei 0dde74f99e channeld: don't forget channels that we've put funds into
Typically we forget a channel if 2016 blocks have passed and
the funding transaction hasn't been mined yet, however we
SHOULD NOT forget these channels if we've got funds in them!
