serpent: add parallel processing for CFB decryption
* cipher/cipher.c (gcry_cipher_open): Add bulf CFB decryption function
for Serpent.
* cipher/serpent-sse2-amd64.S (_gcry_serpent_sse2_cfb_dec): New
function.
* cipher/serpent.c (_gcry_serpent_sse2_cfb_dec): New prototype.
(_gcry_serpent_cfb_dec) New function.
(selftest_cfb_128) New function.
(selftest) Call selftest_cfb_128.
* src/cipher.h (_gcry_serpent_cfb_dec): New prototype.
