And deprecate the --max-locktime-blocks which allows them to set it.
Hilariously, the spec misspells CLTV as CTLV at one point, so we work around it for now.

They're cheap. The 2x channels heuristic is nice, but does assume
they restart every so often. If someone hits 64k connections I would
like to know anyway!
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
1024 is a common limit, and people are starting to hit that many channels, so we should increase it: twice the number of channels seems reasonable, though we only do this at restart time.
Changelog-Changed: lightningd: we now try to increase the number of file descriptors, if it's less than twice the number of channels at startup (and log if we cannot!).

This is fixing a bug that @chrisguida reported,
when we notify a plugin we also notify a plugin
that it is in the middle of initialization.
So imagine the following use case:
- 1. Plugin A sends get manifest
- 2. cln makes a check and generates a warning
- 3. Plugin A is subscribed to the warning or * notification
- 4. Core Lightning gets upset because it receives a warning message but it was waiting for a init.
I think it is still a bug in how Core Lightning handles the init, but also I think we should communicate with the plugin only if it is initialized.

Temporary patch to avoid issue #6973
[ Add much more logging! --RR ]
Changelog-Fixed: lightningd: avoid crash on signing failure when trying to spend anchor outputs.
We wire through --dev options into the hsmd, and test preapprove accept and deby

Apparently VLS actually does something when we preapprove: if caller is just
checking we want to tell it not to do that!
I put in a flag so we can test both old and new APIs.

Now we can check that the setconfig would actually parse. We do this
by handing NULL to the calback to indicate it's a test, which may not
work in general but works for now.

Changelog-Added: `check` `setconfig` now checks that the new config setting would be valid.
We need to pass through setconfig in check mode, then we need to have libplugin
add (and use!) a `check_only` parameter to all option setting.

Changelog-Added: Plugins: Can now opt in to handle `check` command on their commands, for more thorough checking.
If this is set, instead of mangling the request in-place, we will hand
it through raw. Plugins will use this.

We want to extend it to plugins, and we want it to be allowed to be async for more power,
so rather than not completing the cmd if we're checking, do it in command_check_done()
and call it.
This is cleaner than the special case we had before, and allows check to us all the
normal jsonrpc mechanisms, especially async requests (which we'll need if we want to
hand check requests to plugins!).
