Use ccan/opt for commandline parsing. This cleans up option handling, by using ccan/opt rather than handcoded getopt_long. We still have to open-code some things, such as json config file handling. The main change is that the --config option causes a file to be parsed during commandline parsing, so you can override the results, and provide multiple of them. Other improvements are that 'help' and 'ndevs' are not valid arguments in the config file; we use a separate argument table for such commandline-only flags.
