46a643763d Implement fixed-window exponentiation to mitigate hyper-threading 
timing attacks.

BN_FLG_EXP_CONSTTIME requests this algorithm, and this done by default for
RSA/DSA/DH private key computations unless
RSA_FLAG_NO_EXP_CONSTTIME/DSA_FLAG_NO_EXP_CONSTTIME/
DH_FLAG_NO_EXP_CONSTTIME is set.

82e8cb403a Since BN_LLONG will only be defined for Alpha/VMS and not VAX/VMS, 
there's no need to undefine it here.  Then, let's get a bit paranoid
and not define BN_ULLONG on THIRTY_TWO_BIT machines when BN_LLONG
isn't defined.
