[CRYPTO] lrw: Liskov Rivest Wagner, a tweakable narrow block cipher mode
Main module, this implements the Liskov Rivest Wagner block cipher mode in the new blockcipher API. The implementation is based on ecb.c. The LRW-32-AES specification I used can be found at: http://grouper.ieee.org/groups/1619/email/pdf00017.pdf It implements the optimization specified as optional in the specification, and in addition it uses optimized multiplication routines from gf128mul.c. Since gf128mul.[ch] is not tested on bigendian, this cipher mode may currently fail badly on bigendian machines.
