Rusty Russell 4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

ZmnSCPxj jxPCSnmZ d4690358d9 plugins/libplugin.c: Allow freeing notification `struct command *`.
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`.

Rusty Russell 129d3f65e7 pytest: don't use command_success_str in test_libplugin.c
result should *always* be an object.  This allows it to add fields
without breaking the API.  A command which returns "result" as a
string is living in sin.

This changes one of the two callers of "command_success_str".
