Fix various syntax mistakes in files (caused by netctl's renamed logging functions and crude auto-replacements).
Make usage() function available to arg parser (re-order).
Remove traces of using /etc/conf.d/netcfg for reading the fallback interface (netctl has no analogous file/setting).
Remove '-wireless' suffix from all our names.
Again rename; netcfg -> netctl in systemd units.
Fix primary systemd unit contents: we execute auto-ng, not network.
Explicitly return 0 from prepare_wpa_config
Properly separate fields with newlines in prepare_wpa_config.
Beautify min-report: do not output "(in $MODE mode)" if there's no $MODE.
Adjust for netctl: use wpa_wait_until_state instead of wpa_check.
