fix false positives when compiled with msan
...
Our explicit_bzero successfully confused clang -fsanitize-memory
in to thinking that memset is never called to initialise memory.
Ensure that it is called in a way that the compiler recognises.

- (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.
