Is lskcipher only for algorithms that can be computed incrementally? That would
exclude the wide-block modes, and maybe others too. And if so, what is the
model for incremental computation? Based on crypto_lskcipher_crypt_sg(), all
the state is assumed to be carried forward in the "IV". Does that work for all
algorithms? Note that shash has an arbitrary state struct (shash_desc) instead.
