Each header should only include the other headers it needs to compile;
`devtools/reduce-includes.sh */*.h` does this. The C files then need
additional includes if they don't compile.
And remove the entirely useless wire/onion_wire.h, which only serves to include wire/onion_wiregen.h.

Note that we create a destructor on the command to reset request->cmd
pointer if the cmd is freed (so we know not to call the callback).
But attaching hundreds of thousands of them is slow: it's a
single-linked list, which is iterated in several places.
But that's redundant: the request is now allocated off the cmd, so freeing the command
will free the request anyway.
Hacking in something to print progress to a file, here's the number of
requests processed every 10 seconds before and after:

After much thought and mis-steps, I chose a simple solution: open another fd
for sync comms. It's almost impossible to know what state the async one is in.
jsonrpc_request_sync() is enhanced to return a valid tal object, as the current
behaviour of returning a pointer to inside an array was surprising.
Changelog-Changed: libplugin: you can now call the synchronous API functions at any time (not just in the init callback).

All the core notifications changed over to wrapping the notification
fields in an object with the name of the notification, but notifications
from plugins were missed.
Changelog-Added: Plugins: `channel_hint_update`, `pay_failure` and `pay_success` notifications now have objects of the same name containing the expected fields.

This happens with autoclean, which does a datastore request then frees
the parent command without waiting for a response (see clean_finished).
This leaks a trace, and causes a crash if the pointer is later reused.
My solution is to create a trace variant which declares the trace key
to be a tal ptr and then we can clean up in the destructor if this happens.
This fixes the issue for me.

Because we initalized plugin->io_rpc_conn *after* calling plugin->init,
send_outreq would do a (harmless, in our case) wakeup on an uninitialized address:
```
==1164079== Conditional jump or move depends on uninitialised value(s)
==1164079== at 0x1628FC: backend_wake (poll.c:227)
==1164079== by 0x160B98: io_wake (io.c:384)
==1164079== by 0x1160A8: ld_rpc_send (libplugin.c:255)
==1164079== by 0x1187E0: send_outreq (libplugin.c:1099)
==1164079== by 0x115041: init (xpay.c:1620)
```
Solution is simple: set plugin->io_rpc_conn to NULL, and don't wake it in this case.

The `send_outreq` function is a good place to suspend and resume
traces, since these are usually the places where we hand off control
back to the `io_loop`. This assumes that we do not continue doing
heavy liftin after we have queued an `outreq` call, but that is most
likely the case anyway. This frees us from having to track suspensions
whenever we call the RPC from a plugin.
Without knowing what method was called, we can't have useful general logging
methods, so go through the pain of adding "const char *method" everywhere,
and add:
1. ignore_and_complete - we're done when jsonrpc returned
2. log_broken_and_complete - we're done, but emit BROKEN log.
3. plugin_broken_cb - if this happens, fail the plugin.

When we used to allow cmd to be NULL, we had to hand the plugin
everywhere. We no longer do.
1. Various jsonrpc_ functions no longer need the plugin arg.
2. send_outreq no longer needs a plugin arg.
3. The init function takes a command, not a plugin.
4. Remove command_deprecated_in_nocmd_ok.

Sometimes we want to clean up *after* a command has completed, but
we're moving to a model where all libplugin operations require a
`struct command`. This adds `aux_command` to create an

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!).

Uncommited channels are missing several fields which would normally be
populated by an active channel. This simply skips them for the purposes
of finding a route. The particular culprit was:

In this case the cmd is `sql` but the field we're talking about is from
a different command, so we need a new libplugin API.
Note: there are still no deprecations in any tables used by `sql`, so this
is a bit moot for now.

This makes it easier to use outside simple subds, and now lightningd can
simply dump to log rather than returning JSON.
JSON formatting was a lot of work, and we only did it for lightningd, not for
subdaemons. Easier to use the logs in all cases.
