Previous commit was a hack which *always* batched where possible, this
is a more sophisticated opt-in varaint, with a timeout sanity check.
Final performance for cleaning up 1M pays/forwards/invoices:
```
$ time l1-cli autoclean-once succeededpays 1
{
"autoclean": {
"succeededpays": {
"cleaned": 1000000,
"uncleaned": 26895
}
}
}
real 6m9.828s
user 0m0.003s
sys 0m0.001s
$ time l2-cli autoclean-once succeededforwards 1
{
"autoclean": {
"succeededforwards": {
"cleaned": 1000000,
"uncleaned": 40
}
}
}
real 3m20.789s
user 0m0.004s

$ time l3-cli autoclean-once paidinvoices 1

"uncleaned": 0
}
}
}

Changelog-Added: JSON-RPC: `batching` command to allow database transactions to cross multiple back-to-back JSON commands.
This allows GDB to print values, but also allows us to use them in
'case' statements. This wasn't allowed before because they're not
constant terms.
This also made it clear there's a clash between two error codes,
so move one.

Changelog-Changed: JSON-RPC: Error code from bcli plugin changed from 400 to 500.
Build them from the command which caused them, and take plugin name
as basename with extension stripped.

Plugins are supposed to store their data in the datastore, and commando does so:
let's make it easier for them by providing convenience APIs.

We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.
Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

We always allocate a new `struct command` when we get a full JSON
object from stdin:
b2df01dc73/plugins/libplugin.c (L1229-L1233)
If it happens to be a notification, we pass the `struct command` to
the handler, and not free it ourselves:
b2df01dc73/plugins/libplugin.c (L1270-L1275)
There are only nine points in `plugins/libplugin.c` where we `tal_free`
anything, and only one of them frees a `struct command`:
b2df01dc73/plugins/libplugin.c (L224-L234)
The above function `command_complete` is not appropriate for
notification handlers; the above function sends out a response
to our stdout, which a notification handler should not do.
However, as-is, it does mean that notification handling leaks
`struct command` objects, which can be problematic if we ever
have future built-in plugins which are significantly more
dependent on notifications.
This commit changes notification handlers to return
`struct command_result *`, because possibly in the future
notification handlers may want to perform `send_outreq`, so we
might as well use our standard convention for callbacks, and
to encourage future developers to check how to properly
terminate notification handlers (and free up the
`struct command`).
We also now provide a `notification_handled` function which a
notification handler must eventually call, as well as a
`notification_handler_pending` which is just a snowclone of
`command_still_pending`.
We weren't actually getting the last log out; this does that.
We have to fix test_bitcoin_failure which now notices the BROKEN
log message.

Changelog-Fixed: libplugin: Fatal error messages from plugin_exit() now logged in lightningd.
As mentioned in previous commits: "result" must be an object,
and anything else is an antipattern.

Changelog-Fixed: plugin: `bcli` no longer logs a harmless warning about being unable to connect to the JSON-RPC interface.
Changelog-Added: plugin: Plugins can opt out of having an RPC connection automatically initialized on startup.
We don't take the callback result into account, so it can better be void.
Having a general callback parameter is handy, because for bcli we want
to pass it the struct bcli.
This adds helpers to start and send a jsonrpc request using json_stream
in order to benefit from the helpers.
This then simplifies existing plugins RPC requests by using json_stream
helpers.
