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.

7f9c37457a To protect FIPS-related global variables, add locking mechanisms
around them.

NOTE: because two new locks are added, this adds potential binary
incompatibility with earlier versions in the 0.9.7 series.  However,
those locks will only ever be touched when FIPS_mode_set() is called
and after, thanks to a variable that's only changed from 0 to 1 once
(when FIPS_mode_set() is called).  So basically, as long as FIPS mode
hasn't been engaged explicitely by the calling application, the new
locks are treated as if they didn't exist at all, thus not becoming a
problem.  Applications that are built or rebuilt to use FIPS
functionality will need to be recompiled in any case, thus not being a
problem either.

4ed9388e5d A new branch for FIPS-related changes has been created with the name
OpenSSL-fips-0_9_7-stable.

Since the 0.9.7-stable branch is supposed to be in freeze and should
only contain bug corrections, this change removes the FIPS changes
from that branch.

bd573ee31a The OPENSSL_NO_ENGINE has small problem: it changes certain structures. That's
bad, so let's not check OPENSSL_NO_ENGINE in those places.  Fortunately, all
the header files where the problem existed include ossl_typ.h, which makes
a 'forward declaration' of the ENGINE type.

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.

79aa04ef27 Make the necessary changes to work with the recent "ex_data" overhaul.
See the commit log message for that for more information.

NB: X509_STORE_CTX's use of "ex_data" support was actually misimplemented
(initialisation by "memset" won't/can't/doesn't work). This fixes that but
requires that X509_STORE_CTX_init() be able to handle errors - so its
prototype has been changed to return 'int' rather than 'void'. All uses of
that function throughout the source code have been tracked down and
adjusted.

5cbc2e8bc1 Give DH, DSA, and RSA functions to "up" their reference counts. Otherwise,
dependant code has to directly increment the "references" value of each
such structure using the corresponding lock. Apart from code duplication,
this provided no "REF_CHECK/REF_PRINT" checking and violated
encapsulation.

b7727ee616 The indexes returned by ***_get_ex_new_index() functions are used when
setting stack (actually, array) values in ex_data. So only increment the
global counters if the underlying CRYPTO_get_ex_new_index() call succeeds.
This change doesn't make "ex_data" right (see the comment at the head of
ex_data.c to know why), but at least makes the source code marginally less
frustrating.

323f289c48 Change all calls to low level digest routines in the library and
applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().

Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.
