[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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: aead - Fix aead_instance struct size The struct aead_instance is meant to extend struct crypto_instance by incorporating the extra members of struct aead_alg. However, the current layout which is copied from shash/ahash does not specify the struct fully. In particular only aead_alg is present. For shash/ahash this works because users there add extra headroom to sizeof(struct crypto_instance) when allocating the instance. Unfortunately for aead, this bit was lost when the new aead_instance was added. Rather than fixing it like shash/ahash, this patch simply expands struct aead_instance to contain what is supposed to be there, i.e., adding struct crypto_instance. In order to not break existing AEAD users, this is done through an anonymous union. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: aead - pass instance to crypto_grab_aead() Initializing a crypto_aead_spawn currently requires: 1. Set spawn->base.inst to point to the instance. 2. Call crypto_grab_aead(). But there's no reason for these steps to be separate, and in fact this unneeded complication has caused at least one bug, the one fixed by commit 6db43410179b ("crypto: adiantum - initialize crypto_spawn::inst") So just make crypto_grab_aead() take the instance as an argument. To keep the function calls from getting too unwieldy due to this extra argument, also introduce a 'mask' variable into the affected places which weren't already using one.
