 - (djm) [monitor.c sshd.c] SIGXFSZ needs to be ignored in postauth
   monitor, not preauth; bz#2263
 - (djm) [openbsd-compat/explicit_bzero.c] implement explicit_bzero()
   using memset_s() where possible; improve fallback to indirect bzero
   via a volatile pointer to give it more of a chance to avoid being
   optimised away.
