Add asm versions of blowfish and des transforms for i386. This also involved updating the in-kernel DES functions to correspond to the versions in our in-tree OpenSSL, because the des_SPtrans table has changed; the asm code will not work with the old permutation table! C and i386 asm code for the DES, 3DES, and Blowfish CBC modes is also included; it is not currently built as the ESP processing in esp_core.c splits the CBC operation and the cipher transform apart. Hopefully that will be fixed as there is a substantial performance improvement to be had from doing so. It will remain necessary to use the C version of the Blowfish CBC function on some i386 machines, however, as the asm version uses bswapl, which ony 486 and later processors have. The DES CBC code doesn't have this problem. Finally, change esp_core.c to use the ecb3_encrypt function instead of calling ecb_encrypt three times; this improves performance a bit, in particular in the asm case.

sync with kame. - include string.h (instead of sys/systm.h) on userland compilation. make compilation under src/regress/sys/crypto happier. from minoura - (blowfish) KNF.
