c2eadb88be wait: new command to wait on indexes.
This will initially be for listinvoices, but can be expanded to other
list commands.

It's documented, but it makes promises which currently don't exist:

* listinvoice does not support `index` or `start` yet.
* It doesn't actually fire when invoices change yet.

c074fe050f lightningd/log: clean up nomenclature.
`struct log` becomes `struct logger`, and the member which points to the
`struct log_book` becomes `->log_book` not `->lr`.

Also, we don't need to keep the log_book in struct plugin, since it has
access to ld's log_book.

0c4426a349 lightningd: remove deprecated_apis global, put into lightningd.
We usually have access to `ld`, so avoid the global.

The only place generic code needs it is for the json command struct,
and that already has accessors: add one for libplugin and lightningd
to tell it if deprecated apis are OK.

edbaa944da lightningd: switch parsing to common/configvar
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.

6f17d8bf0c lightningd: fix 100% CPU hang on shutdown.
This finally happened on my test box; tests simply stopped.  Turns out
we were spinning here, with waitpid returning -1.

Since this is during shutdown, that also explains why pytest under CI
would hang, since timeouts don't apply during test teardown!

45193db7ea lightningd: add initializing state.
Importantly, the code in jsonrpc.c which actually does the io_break:

```
	/* Once the stop_conn conn is drained, we can shut down. */
	if (jcon->ld->stop_conn == conn && jcon->ld->state == LD_STATE_RUNNING) {
		/* Return us to toplevel lightningd.c */
		log_debug(jcon->ld->log, "io_break: %s", __func__);
		io_break(jcon->ld);
```

By having the state not set until later, we avoid running this.  Of course,
we need to avoid calling the main loop when we get there, if we've already
been told to shutdown.

7b9f1b72c6 lightningd: don't print zero blockheight while we're syncing.
In v0.11 (71f736678f) we changed lightningd to wait for gossipd to
acknowledge blocks before updating blockheight: this resolved a problem
which lnprototest had where it wanted to know when we'd fully digested
a block.

However, it broke the syncing case: until then we don't even tell
gossipd, so this stayed at zero.  We should use the current blockheight
for that corner case!

Fixes: #5894
Changelog-Fixed: JSON-RPC: `getinfo` `blockheight` no longer sits on 0 while we sync with bitcoind the first time.

3f98cf3fce lightningd: track weird CI crash in test_important_plugin
Looks like we woke one of the startup io_loops early, and thus
we thought we'd finished connectd_activate and we hadn't.  This
caused us to use an uninitialized ld->announceable array, and
finally caused an assert fail in the main loop.

Make *every* loop assert that it was exited for the correct reason,
so if it happens again, we can maybe figure out what part of
the code to look at.
