* [whisper] Move needed aes_gcm crypto in-crate In the latest `parity-crypto` release (upcoming 0.4), the aes GCM features were removed (done to remove the dependency on `ring`). This PR adds the bare minimum crypto needed for Whisper directly to the crate itself and as those were the only features needed from `parity-crypto`, removes the dependency on that crate altogether. * Upgrade to parity-crypto 0.4 Reverts using NonZeroU32 (introduced [here](https://github.com/paritytech/parity-ethereum/commit/b347599cf75fefd9fcf9be2b6ba6e8305f8e79ff)). * Check for 0 in `args.arg_keys_iteration` * Use beta.4 * parity-crypto 0.4.0 is released
