[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.

[CRYPTO] api: Get rid of flags argument to setkey Now that the tfm is passed directly to setkey instead of the ctx, we no longer need to pass the &tfm->crt_flags pointer. This patch also gets rid of a few unnecessary checks on the key length for ciphers as the cipher layer guarantees that the key length is within the bounds specified by the algorithm. Rather than testing dia_setkey every time, this patch does it only once during crypto_alloc_tfm. The redundant check from crypto_digest_setkey is also removed.
