[SV 40226] Add a new type of switch: single-string options

Browse source 
* main.c (struct command_switch): Change the "string" types to "strlist"
and make "string" be a single-valued string instead.
(output_sync_option, jobserver_fds, sync_mutex): Change to string type.
(decode_output_sync_flags): Handle single strings instead of lists.
(prepare_mutex_handle_string): Ditto.
(main): Ditto.
(clean_jobserver): Ditto.
(init_switches): Handle the new type.
(decode_switches): Ditto.
(define_makeflags): Ditto.
