07645deeb8 Apply "better safe than sorry" approach after addressing sporadic SEGV in 
bn_sub_words to the rest of the sparcv8plus.S.

c52c82ffc1 Attempt to resolve sporadic SEGV crashes in bn_sub_words in OpenSSH. I'm 
baffled why it crashes and does it sporadically...

bcb43bb358 Yet another "teaser" Montgomery multiply module, for UltraSPARC. It's not 
integrated yet, but it's tested and benchmarked [see commentary section
for further details].

40a3c12305 Initialize bignum constants using BN_bin2bn() instead of BN_hex2bn(). This 
saves a bit of space and avoids a compiler warning about string length.

6f9afa68cd IA-32 BN tune-up. Performance imrpovement varies with platform and 
keylength, this time larger improvement for shorter keys, and reaches
15%. Both SSE2 and IALU code pathes are improved.

EMT64T will hardly exhibit better performance...

8be97c01d1 Decimal printout of a BN is wrong on PPC, it's sparse with very few 
significant digits. As soon it verifies elsewhere it goes to 0.9.8 and
0.9.7.

bb00084863 Replace _int64 with __int64, which is more widely accepted among Win32

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.
