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.

800e400de5 some updates for the blinding code; summary:
- possibility of re-creation of the blinding parameters after a
  fixed number of uses (suggested by Bodo)
- calculatition of the rsa::e in case it's absent and p and q
  are present (see bug report #785)
- improve the performance when if one rsa structure is shared by
  more than a thread (see bug report #555)
- fix the problem described in bug report #827
- hide the definition ot the BN_BLINDING structure in bn_blind.c

9c52d2cc75 After the latest round of header-hacking, regenerate the dependencies in
the Makefiles. NB: this commit is probably going to generate a huge posting
and it is highly uninteresting to read.

0f814687b9 Deprecate the recursive includes of bn.h from various API headers (asn1.h,
dh.h, dsa.h, ec.h, ecdh.h, ecdsa.h, rsa.h), as the opaque bignum types are
already declared in ossl_typ.h. Add explicit includes for bn.h in those C
files that need access to structure internals or API functions+macros.

8a85c341fe The problem of rsa key-generation getting stuck in a loop for (pointlessly)
small key sizes seems to result from the code continually regenerating the
same prime value once the range is small enough. From my tests, this change
fixes the problem by setting an escape velocity of 3 repeats for the second
of the two primes.
