e auth - use our memclear and fill it out with modern zeroing methods
so memset_s still doesn't get detected (add a check anyway), but there
are other alternatives, so detect and use them if found
(explicit_bzero, explicit_memset) in addition to the generally
"practically works" memset ptr method we had and.. just to be extra
safe add an asm memory barrier to this fallback. also.. mlock the
passwd memory in lokker (if it doesn't work - don't worry - there is
nothing we can do, so we did our best) to avoid this memory gettign
swapped etc.
