There is an undocumented (at least in terms of a manpage) function named
shutdown_nice() in sys/kern/kern_shutdown.c that will send a signal to
the init process if it's running or call boot(9) if not.  Or maybe a
direct call to boot(9) is what you're looking for, if bypassing the
running of rc shutdown scripts and all is your goal.  (There is a mapage
for boot(9)).
