d29ce988ae [CRYPTO] aead: Create default givcipher instances
This patch makes crypto_alloc_aead always return algorithms that is
capable of generating their own IVs through givencrypt and givdecrypt.
All existing AEAD algorithms already do.  New ones must either supply
their own or specify a generic IV generator with the geniv field.

5b6d2d7fdf [CRYPTO] aead: Add aead_geniv_alloc/aead_geniv_free
This patch creates the infrastructure to help the construction of IV
generator templates that wrap around AEAD algorithms by adding an IV
generator to them.  This is useful for AEAD algorithms with no built-in
IV generator or to replace their built-in generator.
