crypto: shash - Require all algorithms to support export/import
This patch provides a default export/import function for all shash algorithms. It simply copies the descriptor context as is done by sha1_generic. This in essence means that all existing shash algorithms now support export/import. This is something that will be depended upon in implementations such as hmac. Therefore all new shash and ahash implementations must support export/import. For those that cannot obtain a partial result, padlock-sha's fallback model should be used so that a partial result is always available. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
