Adds the zeroize dependency and clears the retained ChaCha20-Poly1305 key on CipherState, the chaining key and handshake hash on SymmetricState, and the 64-byte HKDF outputs in mix_key and split along with the two session keys split derives. The key mix_key derives for the handshake cipher is cleared too: it is passed by value into a Copy parameter, so the caller's copy survives the call and is the same class of residue as the ones beside it. Three fields are deliberately left out. The cached LessSafeKey holds its material behind ring's API and cannot be cleared from here, and the nonce and the has-key flag are not secret. Also corrects the comments around this code, which were wrong in ways that would have made the change harder to reason about later. ring's LessSafeKey does implement Clone; UnboundKey is the one that does not, and two comments said otherwise while a third said the opposite. The key bytes are retained for Clone and cipher_clone, not for initialize_key, which builds from its own argument. Caching the keyed cipher does not skip Poly1305 key derivation, which is nonce-dependent and happens per message. And the construction it does skip is a length check and a word conversion, not a constant-time check. The HKDF state itself, the ephemeral private key, and the per-handshake DH outputs are still uncleared; those are separate changes.
