Zero memory in CRYPTO_secure_malloc.



This commit destroys the free list pointers which would otherwise be
present in the returned memory blocks.  This in turn helps prevent
information leakage from the secure memory area.

Note: CRYPTO_secure_malloc is not guaranteed to return zeroed memory:
before the secure memory system is initialised or if it isn't implemented.
