I wanted to move saved_arg[cv] to process-util.c+h, but this causes problems: process-util.h includes format-util.h which includes net/if.h, which conflicts with linux/if.h. So we can't include process-util.h in some files. But process-util.c is very long anyway, so it seems nice to create a new file. rename_process(), invoked_as(), invoked_by_systemd(), and argv_looks_like_help() which lived in process-util.c refer to saved_argc and saved_argv, so it seems reasonable to move them to the new file too. util.c is now empty, so it is removed. util.h remains.
