The XTS (XEX with tweaked-codebook and ciphertext stealing) cipher mode is commonly used in full disk encryption. There is unfortunately no implementation of it in either libgcrypt or nettle, so we need to provide our own. The libtomcrypt project provides a repository of crypto algorithms under a choice of either "public domain" or the "what the fuck public license". So this impl is taken from the libtomcrypt GIT repo and adapted to be compatible with the way we need to call ciphers provided by nettle/gcrypt.
