[CRYPTO] api: Added crypto_type support
This patch adds the crypto_type structure which will be used for all new
crypto algorithm types, beginning with block ciphers.
The primary purpose of this abstraction is to allow different crypto_type
objects for crypto algorithms of the same type, in particular, there will
be a different crypto_type objects for asynchronous algorithms.
