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

Modified version of the commit ffaef3f1

 in the master branch by Stephen
Henson. This makes the SSL_OP_SINGLE_DH_USE option a no-op and always
generates a new DH key for every handshake regardless.

CVE-2016-0701 (fix part 2 or 2)

Issue reported by Antonio Sanso

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

Calling SSL_shutdown while in init previously gave a "1" response, meaning
everything was successfully closed down (even though it wasn't). Better is
to send our close_notify, but fail when trying to receive one.

The problem with doing a shutdown while in the middle of a handshake is
that once our close_notify is sent we shouldn't really do anything else
(including process handshake/CCS messages) until we've received a
close_notify back from the peer. However the peer might send a CCS before
acting on our close_notify - so we won't be able to read it because we're
not acting on CCS messages!

For BSD systems, Configure adds a shared_ldflags including a reference
to the Makefile variable LIBRPATH, but since it must be passed down to
Makefile.shared, care must be taken so the value of LIBRPATH doesn't
get expanded too early, or it ends up giving an empty string.

Error in the definition of the macro SSL_set1_sigalgs(ctx, slist,
slistlen): the third parameter 'slistlen' not used in the substitution
code; used 'clistlen' instead. As a result of this, compilation error
occurs when any application uses this macro.

Describe the usage of the OCSP callback functions on both the client and
the server side.

Reviewed-by: Viktor Dukhovni <viktor@openssl.org>

It makes no sense to call the OCSP status callback if we are resuming a
session because no certificates will be sent.

Reviewed-by: Viktor Dukhovni <viktor@openssl.org>

If a server sends the status_request extension then it may choose
to send the CertificateStatus message. However this is optional.
We were treating it as mandatory and the connection was failing.

Thanks to BoringSSL for reporting this issue.

This also changes BIO_C_GET_CONNECT to actually return the port
