Currently, "cipher" (single-block cipher) spawns are usually initialized by using crypto_get_attr_alg() to look up the algorithm, then calling crypto_init_spawn(). In one case, crypto_grab_spawn() is used directly. The former way is different from how skcipher, aead, and akcipher spawns are initialized (they use crypto_grab_*()), and for no good reason. This difference introduces unnecessary complexity. The crypto_grab_*() functions used to have some problems, like not holding a reference to the algorithm and requiring the caller to initialize spawn->base.inst. But those problems are fixed now. Also, the cipher spawns are not strongly typed; e.g., the API requires that the user manually specify the flags CRYPTO_ALG_TYPE_CIPHER and CRYPTO_ALG_TYPE_MASK. Though the "cipher" algorithm type itself isn't yet strongly typed, we can start by making the spawns strongly typed. So, let's introduce a new 'struct crypto_cipher_spawn', and functions crypto_grab_cipher() and crypto_drop_cipher() to grab and drop them. Later patches will convert all cipher spawns to use these, then make crypto_spawn_cipher() take 'struct crypto_cipher_spawn' as well, instead of a bare 'struct crypto_spawn' as it currently does.
