[CRYPTO] digest: Added user API for new hash type The existing digest user interface is inadequate for support asynchronous operations. For one it doesn't return a value to indicate success or failure, nor does it take a per-operation descriptor which is essential for the issuing of requests while other requests are still outstanding. This patch is the first in a series of steps to remodel the interface for asynchronous operations. For the ease of transition the new interface will be known as "hash" while the old one will remain as "digest". This patch also changes sg_next to allow chaining.

crypto: hash - Move ahash functions into crypto/hash.h All new crypto interfaces should go into individual files as much as possible in order to ensure that crypto.h does not collapse under its own weight. This patch moves the ahash code into crypto/hash.h and crypto/internal/hash.h respectively. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: hash - Fixed digest size check The digest size check on hash algorithms is incorrect. It's perfectly valid for hash algorithms to have a digest length longer than their block size. For example crc32c has a block size of 1 and a digest size of 4. Rather than having it lie about its block size, this patch fixes the checks to do what they really should which is to bound the digest size so that code placing the digest on the stack continue to work. HMAC however still needs to check this as it's only defined for such algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
