plugin: Iterate over the options from a plugin using the tok->size 
I had this really contorted way of iterating over options that could
cause valgrind to choke. This is the much more intuitive way to
iterate.

plugin: Map results back to the incoming JSON-RPC request

the plugin back to the original request we got from the client.

We weren't cleaning the requests we fulfilled, so this does that :-)

e6ef675ea1 plugin: Send the configure request once we collected all options 
This is the final step to get the plugins working. After parsing the
early options (including `--plugin`), then starting and asking the
plugins for options, and finally reading in the options we just
registered, we just need to assemble the options and send them over.

3abc32cbbc plugin: Terminate objects with an empty line to signal end 
This is just meant as a hint to the plugin that the message is done,
and it can try to parse the buffer.

55d6d6b0e7 plugin: Register plugin cli options 
We also make `--help` a non-early arg so it allows for the plugins to
register their options before printing the help message. The options
themselves are stored in a separate struct inbetween them being
registered and them being forwarded to the plugin. Currently only
supports string options.
