This matches dm-crypt use of EBOIV to provide BitLocker support, and so it is proposed as a replacement in patch #3. Replacing the dm-crypt specific EBOIV implementation to a Crypto API based one allows us to save a memory allocation per each request, as well as opening the way for use of compatible alternative transform providers, one of which, based on the Arm TrustZone CryptoCell hardware, is proposed as patch #4. Future potential work to allow encapsulating the handling of multiple subsequent blocks by the Crypto API may also benefit from this work. The code has been tested on both x86_64 virtual machine with the dm-crypt test suite and on an arm 32 bit board with the CryptoCell hardware. Since no offical source for eboiv test vectors is known, the test vectors supplied as patch #2 are derived from sectors which are part of the dm-crypt test suite.
