Title: Use a pointer to state in _update and _final

The functions `crypto_hash_sha256_update` and `crypto_hash_sha256_final` take a
pointer to `state` as their first arguments, however the documentation showed
an example of passing state directly by-value. This is incorrect and won't
compile. This patch corrects the documentation by passing a pointer.
