[CRYPTO] api: Add aead crypto type
This patch adds crypto_aead which is the interface for AEAD (Authenticated Encryption with Associated Data) algorithms. AEAD algorithms perform authentication and encryption in one step. Traditionally users (such as IPsec) would use two different crypto algorithms to perform these. With AEAD this comes down to one algorithm and one operation. Of course if traditional algorithms were used we'd still be doing two operations underneath. However, real AEAD algorithms may allow the underlying operations to be optimised as well.
