crypto: implement the LUKS block encryption format

Provide a block encryption implementation that follows the LUKS/dm-crypt specification. This supports all combinations of hash, cipher algorithm, cipher mode and iv generator that are implemented by the current crypto layer. There is support for opening existing volumes formatted by dm-crypt, and for formatting new volumes. In the latter case it will only use key slot 0.
