[CRYPTO] api: Add crypto_inc and crypto_xor With the addition of more stream ciphers we need to curb the proliferation of ad-hoc xor functions. This patch creates a generic pair of functions, crypto_inc and crypto_xor which does big-endian increment and exclusive or, respectively. For optimum performance, they both use u32 operations so alignment must be as that of u32 even though the arguments are of type u8 *. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
