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

It seems that Test::More doesn't like 0 tests, a line like this raises
an error and stops the recipe entirely:

So we need to check for 0 tests beforehand and skip the subtest

Also removes the make variable SHARED_LIBS_LINK_EXTS, only used by
the clean-shared target.

When shared library linking was moved to the separate Makefile.shared
in commit 30afcc07

, this target was
skipped.  Prior to that commit, clean-shared was invoked as a
dependency of build-shared, but afterward it was no longer referenced
anywhere in the tree.

Instead of porting the functionality over to Makefile.shared, just
remove it entirely, as it appears to be unused.
