crypto: import an implementation of the XTS cipher mode 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.

crypto: refactor XTS cipher mode test suite The current XTS test overloads two different tests in a single function making the code a little hard to follow. Split it into distinct test cases. Reviewed-by: Alberto Garcia <berto@igalia.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
