Replace the eay DES code with key scheule setup code by me and DES

s-box and p permutation from Richard Outerbridge implemtation (in
public domain).  The DES modes are implemented by me. ui.c code are
from appl/login.

The implementation is about 3 times slower then Eric for encryption,
and about the same speed for key setup.
