The XTS template now wraps an ECB mode algorithm rather than the block cipher directly.

Add a function to crypto_simd that registers an array of skcipher algorithms, then allocates and registers the simd wrapper algorithms for them. It assumes the naming scheme where the names of the underlying algorithms are prefixed with two underscores. Also add the corresponding 'unregister' function.
