Commit 9ceb2426 (PACKETise ClientHello) broke session tickets by failing

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
was causing a compilation failure when config'd with

Two tests are added: one is a simple version tolerance test; the second is
a test to ensure that OpenSSL operates correctly in the case of a zero
length extensions block. The latter was broken inadvertently (now fixed)
and it would have been helpful to have a test case for it.

This commit provides a set of perl modules that support the testing of
libssl. The test harness operates as a man-in-the-middle proxy between
s_server and s_client. Both s_server and s_client must be started using the
"-testmode" option which loads the new OSSLTEST engine.

The test harness enables scripts to be written that can examine the packets
sent during a handshake, as well as (potentially) modifying them so that
otherwise illegal handshake messages can be sent.

This engine is for testing purposes only. It provides crippled crypto
implementations and therefore must not be used in any instance where
security is required.

This will be used by the forthcoming libssl test harness which will operate
as a man-in-the-middle proxy. The test harness will be able to modify
TLS packets and read their contents. By using this test engine packets are
not encrypted and MAC codes always verify.

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.
Reviewed-by: NRichard Levitte <levitte@openssl.org>

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.
