Daniel P. Berrange eaec903c5b crypto: wire up XTS mode for cipher APIs
Introduce 'XTS' as a permitted mode for the cipher APIs.
With XTS the key provided must be twice the size of the
key normally required for any given algorithm. This is
because the key will be split into two pieces for use
in XTS mode.
