Trouble is that LINK variable assignment in make-file interferes with
LINK environment variable, which can be used to modify Microsoft's
LINK.EXE behaviour.

CVE-2015-3197

Reviewed-by: Tim Hudson <tjh@openssl.org>

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.

This is a follow on from CVE-2016-0701. This branch is not impacted by
that CVE because it does not support X9.42 style parameters. It is still
possible to generate parameters based on primes that are not "safe",
although by default OpenSSL does not do this. The documentation does
sign post that using such parameters is unsafe if the private DH key is
reused. However to avoid accidental problems or future attacks this commit
has been backported to this branch.

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.

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

Reviewed-by: Viktor Dukhovni <viktor@openssl.org>
(cherry picked from commit c52c3b5e)

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>
(cherry picked from commit 0ac62399)

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.

BIO_int_ctrl isn't made for the purpose BIO_get_conn_int_port used it

This also changes BIO_C_GET_CONNECT to actually return the port
instead of assigning it to a pointer that was never returned back to

If using DTLS and NBIO then if a second or subsequent handshake message
fragment hits a retry, then the retry attempt uses the wrong fragment
offset value. This commit restores the fragment offset from the last
