[CRYPTO] salsa20: Salsa20 stream cipher
This patch implements the Salsa20 stream cipher using the blkcipher interface. The core cipher code comes from Daniel Bernstein's submission to eSTREAM: http://www.ecrypt.eu.org/stream/svn/viewcvs.cgi/ecrypt/trunk/submissions/salsa20/full/ref/ The test vectors comes from: http://www.ecrypt.eu.org/stream/svn/viewcvs.cgi/ecrypt/trunk/submissions/salsa20/full/ It has been tested successfully with "modprobe tcrypt mode=34" on an UML instance.
