[CRYPTO] twofish: Split out common c code
This patch splits up the twofish crypto routine into a common part ( key setup ) which will be uses by all twofish crypto modules ( generic-c , i586 assembler and x86_64 assembler ) and generic-c part. It also creates a new header file which will be used by all 3 modules. This eliminates all code duplication. Correctness was verified with the tcrypt module and automated test scripts.
