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 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
By default, we won't close a channel that we leased to a peer.
You can override this with the `force_lease_closed` flag.

Changelog-Added: JSON-RPC: close now has parameter to force close a leased channel (option_will_fund)

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!

niftynei 43ae30df21 chaintopology: new command 'parsefeerate'
Useful for parsing a passed in feerate before calling lightningd with

niftynei 376e6f8bd1 dual-funding: update fee_step to be a feerate
Using a 'feestep' is more restrictive than you'd want, instead we
enforce that the next feerate must be at least 1/64th more than the
last, but put no upper limit on it

Includes update to lnprototest changes

Christian Decker ce66466cfb opts: Add option to register extra TLV types to accept
Incoming HTLCs are rejected by the HTLC logic if the payload contains
an even type that `lightningd` doesn't recognize. This is to prevent
us from accidentally accepting a payment that has extra semantics
attached (for example if we get a keysend payment and don't know what
to do with the TLV field containing the message we should reject it,
otherwise the overall semantics of the message delivery fail).

Rusty Russell 8f33f46960 closingd: use a more accurate fee for closing fee negotiation.
We were actually using the last commit tx's size, since we were
setting it in lightningd.  Instead, hand the min and desired feerates
to closingd, and (as it knows the weight of the closing tx), and have
it start negotiation from there.

This can be significantly less when anchor outputs are enabled: for
example in test_closing.py, the commit tx weight is 1124 Sipa, the
close is 672 Sipa!
