[CRYPTO] api: Allow algorithm lookup by type
This patch also adds the infrastructure to pick an algorithm based on their type. For example, this allows you to select the encryption algorithm "aes", instead of any algorithm registered under the name "aes". For now this is only accessible internally. Eventually it will be made available through crypto_alloc_tfm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
