When core lightning is asking the information about
the blockchain with `getchaininfo` command lightningd
know already the information about the min and max block height.
the problem is when we have a smarter Bitcoin backend that is able
to switch between different clients in some cases is helpful
give the information about current known height by lightningd and
pass it down to the plugin.
In this way, the plugin knows what is the correct known height from lightnind, and can
try to fix some problems if any exit.
This is particularly useful when you are syncing a new backend from scratch
like https://github.com/cloudhead/nakamoto and we avoid returning the
lower height from the known, and avoid the crash of core lightning.
With this information, the plugin can start to sync the chain and return
the answer back only when the chain is in sync with the current status of
lightningd.
Another reason to add this field and not wait the correct block in core
lightning itself is because Bitcoin Core is extremely slow to sync up,
so the question here is, how long should we wait? The time depends
on various factors.
With this approach of informing the plugin about the height, in some cases,
you can start the syncing but move the execution to another backend until
the previous one is ready.
The problem I want to solve is that I don't want to be left in the dark when
we run `getchaininfo`, and I want to have the opportunity to wait for
the blockchain sync or decide to dispatch the request elsewhere.
Changelog-Added: Pass the current known block height down to the getchaininfo call.

This integrates them with configvars properly: they almost "just work"

Changelog-Deprecated: Config: boolean plugin options set to `1` or `0` (use `true` and `false` like non-plugin options).
Now we wire in the code which gathers configvars and parses from there;
lightningd keeps the array of configuration variables for future use.
Note that lightning-cli also needs to read the config, but it has its
own options (including short ones!) and doesn't want to use this
configvar mechanism, so we have a different API for that now.

Now we've set everything up, the replacement code is quite simple.
Some tests now have to deal with RBF though, and our rbf tests need work
since they look for the old onchaind messages.
In particular, when we can't afford the fee we want, we back off to
the next blockcount estimate, rather than spending all on fees
(necessarily). So test_penalty_rbf_burn no longer applies.

When a channel open fails, we use tx-abort instead of warning/error.
This means that the peer won't disconnect! And instead when a new
message arrives, we'll need to rebuild the dualopend subd (if missing).
Makes opens a bit easer to retry (no reconnect needed), as well as keeps
the connection alive for other channels we may have with that peer.
Changelog-Changed: Experimental-Dual-Fund: open failures don't disconnect, but instead fail the opening process
I noticed that our subtables were not being cleaned, despite being "ON
DELETE CASCADE". This is because foreign keys were not enabled, but
then I got foreign key errors: rowid cannot be a foreign key anyway!
So create a real "rowid" column. We want "ON DELETE CASCADE" for
nodes and channels (and other tables in future) where we update
partially.

This avoids any confusion between primitive and string ids, and in
particular stops an issue with commando once it starts chaining ids,
that weird ids can be double-escaped and commando will not recognize
the response, leaving the client hanging. It's the client's fault for
using a weird id, but it's still rude (and triggered by our tests!).
It also makes substituting the id in passthrough simpler, FTW.

This is a minimal fix: we wait until all plugins reply from init before
continuing. Really large or busy nodes can have other things monopolize
lightningd, then the timer goes off and we blame the plugin (which has
responded, we just haven't read it yet!).
The real answer is to have some timeouts only advance when we're idle,
or have them low-priority so we only activate them when we're idle (this
doesn't apply to all timers: some are probably important!). But
this is a minimal fix for -rc3.
