We now hand around struct json_out members, rather than using formatted
strings, so plugins need to construct them properly.
There's no automatic conversion between ' and " any more, so those
are eliminated too. pay still uses some manual construction of elements.

1. Allow timers to be freed in their callback.
2. Clarify in header that we have to terminate our timer with timer_finished()
eventually.
3. We don't currently have plugins with more than one outstanding timer, but
it certainly would be possible, so fix in_timer to be a counter.
