systemctl: convert verbs to VERB macros
systemctl_main() is moved to systemctl.c to allow fuzz-systemctl-parse-argv to compile. It needs systemctl_help(), which needs the verb table, with the expected groups. Once we provide that, the linker needs all the verb_* functions. So add dummy implementations in fuzz-systemctl-parse-argv to allow the link to happen. The alternative would be to provide an empty option table, but that seems to be more complicated, and also can simulate parsing of the whole command line with the full verb set, so it seems better to test with the real verb table. $ nm build/fuzz-systemctl-parse-argv | rg 0000000000418885 0000000000418885 T verb_add_dependency 0000000000418885 T verb_bind 0000000000418885 T verb_cancel 0000000000418885 T verb_cat 0000000000418885 T verb_clean_or_freeze 0000000000418885 T verb_edit 0000000000418885 T verb_enable 0000000000418885 T verb_get_default 0000000000418885 T verb_import_environment 0000000000418885 T verb_is_active 0000000000418885 T verb_is_enabled 0000000000418885 T verb_is_failed 0000000000418885 T verb_is_system_running 0000000000418885 T verb_kill 0000000000418885 T verb_list_automounts 0000000000418885 T verb_list_dependencies 0000000000418885 T verb_list_jobs 0000000000418885 T verb_list_machines 0000000000418885 T verb_list_paths 0000000000418885 T verb_list_sockets 0000000000418885 T verb_list_timers 0000000000418885 T verb_list_unit_files 0000000000418885 T verb_list_units 0000000000418885 T verb_log_setting 0000000000418885 T verb_mount_image 0000000000418885 t verb_noop 0000000000418885 T verb_preset_all 0000000000418885 T verb_reset_failed 0000000000418885 T verb_service_log_setting 0000000000418885 T verb_service_watchdogs 0000000000418885 T verb_set_default 0000000000418885 T verb_set_environment 0000000000418885 T verb_set_property 0000000000418885 T verb_show 0000000000418885 T verb_show_environment 0000000000418885 T verb_start_special 0000000000418885 T verb_start_system_special 0000000000418885 T verb_switch_root 0000000000418885 T verb_trivial_method 0000000000418885 T verb_whoami
