Rusty Russell a01216505f common: add new param_check() which doesn't abort if we're simply checking.
We often want to do more parameter checks after param(), so allow a
new param_check(), with the proviso that the caller needs to also return
command_check_done() after other checks if command_check_only(cmd) is true.

Rusty Russell eeee5d6249 lightningd: really fill in our own details when channeld says to make channel_update.
Now we've asserted that channeld would tell lightningd the same thing it
would do anyway, we can simply have channeld say "enable=True|False" and
lightningd fill in the other fields.

This means there's a pile of things channeld doesn't need to know any more!

Rusty Russell 9c04d0b02d lightningd: make sure that channeld_local_channel_update fields are redundant.
channeld used to talk directly to gossipd, so it made sense for it to
tell gossipd directly when it wanted it to make a new channel_update.

When that changed with v0.11, we simply directed the message via
lightningd.

But much of the information is actually told to channeld by lightningd!

So I applied this assertion and ran the test suite, before the next patch makes it redundant.

We got one assertion: test_setchannel_zero deliberately drives the
advertized htlc_max over the real htlc max in test_setchannel_zero for
testing.

Rusty Russell db7f59eeba lightningd: simplify plugin hook handling.
Now the internal code will generate a "PLUGIN_TERMINATED" response
when the plugin dies, we can handle it in plugin_hook.

But we can also simplify it by turning the snapshot of hooks into
a simple array: this means we are robust against any combination of plugins
exiting at any time.

Note: this reveals an issue with test_rpc_command_hook where we run
the request hook again (unexpectedly), so we disable that for the next
patch.

We had special code to fail a forwarded request, but not for an
internally-generated request.  Instead, we should pretend the (dead)
plugin responded with a PLUGIN_TERMINATED error, and handle the
request through the normal paths.

This breaks the case where a plugin crashes (or stops itself) in a
hook, so we handle that next.

During the changeset calculation after the `openchannel2_sign`
hook.

So this commit patch the problem with the following change:

- Addressed an issue where `psbt_get_changeset` was modifying the original PSBT unnecessarily.
- This modification led to problems with a different hsmd, as referenced in [Issue #6672](https://github.com/ElementsProject/lightning/issues/6672).
- Noted a potential optimization where only a subpart of the PSBT
needs to be cloned, as the mutation is specific to inputs.
