Not all architectures have a time_t defined the same way. To make
sure we get the same result, we need to cast &checkoffset to (intmax_t *)
and make sure that intmax_t is defined somehow.
To make really sure we don't pass a variable with the wrong size down
to opt_imax(), we use a temporary intmax_t.

As a side-effect of opaque x509, ex_flags were looked up too early,
before additional policy cache updates.
Reviewed-by: Dr. Stephen Henson <steve@openssl.org>
The lflags configuration had a weird syntax with a % as separator. If
it was present, whatever came before ended up as PEX_LIBS in Makefile
(usually, this is LDFLAGS), while whatever came after ended up as
EX_LIBS.
This change splits that item into lflags and ex_libs, making their use
more explicit.
Also, PEX_LIBS in all the Makefiles are renamed to LDFLAGS.

By default X509_check_trust() trusts self-signed certificates from
the trust store that have no explicit local trust/reject oids
encapsulated as a "TRUSTED CERTIFICATE" object. (See the -addtrust
and -trustout options of x509(1)).
This commit adds a flag that makes it possible to distinguish between
that implicit trust, and explicit auxiliary settings.
With flags |= X509_TRUST_NO_SS_COMPAT, a certificate is only trusted
via explicit trust settings.

The use of the uninitialized buffer in the RNG has no real security

Add tests for have_precompute_mult for the optimised curves (nistp224,
nistp256 and nistp521) if present
Reviewed-by: Richard Levitte <levitte@openssl.org>
During precomputation if the group given is well known then we memcpy a
well known precomputation. However we go the wrong label in the code and
don't store the data properly. Consequently if we call have_precompute_mult
the data isn't there and we return 0.

The function DH_check_pub_key() was missing some return value checks in
some calls to BN functions.
RT#4278
Reviewed-by: Andy Polyakov <appro@openssl.org>
A new return value for DH_check_pub_key was recently added:
DH_CHECK_PUBKEY_INVALID. As this is a flag which can be ORed with other
return values it should have been set to the value 4 not 3.

Following on from the previous commit, add a test to ensure that
DH_compute_key correctly fails if passed a bad y such that:
y^q (mod p) != 1
Reviewed-by: Viktor Dukhovni <viktor@openssl.org>
Historically OpenSSL only ever generated DH parameters based on "safe"
primes. More recently (in version 1.0.2) support was provided for
generating X9.42 style parameter files such as those required for RFC
5114 support. The primes used in such files may not be "safe". Where an
application is using DH configured with parameters based on primes that
are not "safe" then an attacker could use this fact to find a peer's
private DH exponent. This attack requires that the attacker complete
multiple handshakes in which the peer uses the same DH exponent.
A simple mitigation is to ensure that y^q (mod p) == 1
