When config'd with "sctp" running "make test" causes a seg fault. This is
actually due to the way ssltest works - it dives under the covers and frees
up BIOs manually and so some BIOs are NULL when the SCTP code does not
expect it. The simplest fix is just to add some sanity checks to make sure
the BIOs aren't NULL before we use them.

This problem occurs in master and 1.0.2. The fix has also been applied to
1.0.1 to keep the code in sync.

There are some missing return value checks in the SCTP code. In master this

The function BN_MONT_CTX_set was assuming that the modulus was non-zero
and therefore that |mod->top| > 0. In an error situation that may not be
the case and could cause a seg fault.

This is a follow on from CVE-2015-1794.

If a client receives a ServerKeyExchange for an anon DH ciphersuite with the
value of p set to 0 then a seg fault can occur. This commits adds a test to
reject p, g and pub key parameters that have a 0 value (in accordance with
RFC 5246)

The security vulnerability only affects master and 1.0.2, but the fix is
additionally applied to 1.0.1 for additional confidence.

The DTLS code is supposed to drop packets if we try to write them out but
the underlying BIO write buffers are full. ssl3_write_pending() contains
an incorrect test for DTLS that controls this. The test only checks for
DTLS1 so DTLS1.2 does not correctly clear the internal OpenSSL buffer which
can later cause an assert to be hit. This commit changes the test to cover
all DTLS versions.

The function SSL_set_session_ticket_ext can be used to set custom session
ticket data passed in the initial ClientHello. This can be particularly
useful for EAP-FAST. However, when using SSLv23_method, the session does
not get created until the ServerHello has been received. The extension code
will only add the SessionTicket data to the ClientHello if a session already
exists. Therefore SSL_set_session_ticket_ext has no impact when used in
conjunction with SSLv23_method. The solution is to simply create the session
during creation of the ClientHello instead of waiting for the ServerHello.

This commit fixes the test failure introduced by the previous commit.
