ecb1445ce2 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.

4ed56cba63 New function BN_MONT_CTX_set_locked, to set montgomery parameters in a
threadsafe manner.

Modify or add calls to use it in rsa, dsa and dh algorithms.

27310553b1 We seem to carry some rests of the 0.9.6 [engine] ENGINE framework in form
of unneeded includes of openssl/engine.h.

cb78486d97 This commits changes to various parts of libcrypto required by the recent
ENGINE surgery. DH, DSA, RAND, and RSA now use *both* "method" and ENGINE
pointers to manage their hooking with ENGINE. Previously their use of
"method" pointers was replaced by use of ENGINE references. See
crypto/engine/README for details.

Also, remove the ENGINE iterations from evp_test - even when the
cipher/digest code is committed in, this functionality would require a
different set of API calls.

9b141126d4 New functions BN_CTX_start(), BN_CTX_get(), BN_CTX_end() to access
temporary BIGNUMs. BN_CTX still uses a fixed number of BIGNUMs, but
the BN_CTX implementation could now easily be changed.
