The function SSL_get_shared_ciphers() is supposed to return ciphers shared

Commit d316cdcf6d introduced some extra
checks into the session-cache update procedure, intended to prevent
the caching of sessions whose resumption would lead to a handshake
failure, since if the server is authenticating the client, there needs to
be an application-set "session id context" to match up to the authentication
context. While that change is effective for its stated purpose, there
was also some collatoral damage introduced along with the fix -- clients
that set SSL_VERIFY_PEER are not expected to set an sid_ctx, and so
their usage of session caching was erroneously denied.
Fix the scope of the original commit by limiting it to only acting
when the SSL is a server SSL.

In 1.0.2 and below we always send the same client_version in a reneg
ClientHello that we sent the first time around, regardless of what
version eventually gets negotiated. According to a comment in
statem_clnt.c this is a workaround for some buggy servers that choked if
we changed the version used in the RSA encrypted premaster secret.
In 1.1.0+ this behaviour no longer occurs. This restores the original
behaviour.

In 1.0.2 you could configure automatic ecdh params by using the
ECDHParameters config directive and setting it to the value
"+Automatic" or just "Automatic". This is no longer required in 1.1.0+
but we still recognise the "+Automatic" keyword for backwards compatibility.
However we did not recognise just "Automatic" without the leading "+" which
is equally valid. This commit fixes that omission.

The GOST engine needs to be loaded before we initialise libssl. Otherwise
the GOST ciphersuites are not enabled. However the SSL conf module must
be loaded before we initialise libcrypto. Otherwise we will fail to read
the SSL config from a config file properly.
Another problem is that an application may make use of both libcrypto and
libssl. If it performs libcrypto stuff first and OPENSSL_init_crypto()
is called and loads a config file it will fail if that config file has
any libssl stuff in it.
This commit separates out the loading of the SSL conf module from the
interpretation of its contents. The loading piece doesn't know anything
about SSL so this can be moved to libcrypto. The interpretation of what it
means remains in libssl. This means we can load the SSL conf data before
libssl is there and interpret it when it later becomes available.

For DTLS/SCTP we were waiting for a dry event during the call to
tls_finish_handshake(). This function just tidies up various internal
things, and after it completes the handshake is over. I can find no good
reason for waiting for a dry event here, and nothing in RFC6083 suggests
to me that we should need to. More importantly though it seems to be
wrong. It is perfectly possible for a peer to send app data/alerts/new
handshake while we are still cleaning up our handshake. If this happens
then we will never get the dry event and so we cannot continue.

At a couple of points in a DTLS/SCTP handshake we need to wait for a dry

This commit changes things so that we attempt to read a message if we
are waiting for a dry event but haven't got one yet. This should never
succeed, but any alerts will be processed.

The sid_ctx is something of a "certificate request context" or a
"session ID context" -- something from the application that gives
extra indication of what sort of thing this session is/was for/from.
Without a sid_ctx, we only know that there is a session that we
issued, but it could have come from a number of things, especially
with an external (shared) session cache. Accordingly, when resuming,
we will hard-error the handshake when presented with a session with
zero-length sid_ctx and SSL_VERIFY_PEER is set -- we simply have no
information about the peer to verify, so the verification must fail.
In order to prevent these future handshake failures, proactively
decline to add the problematic sessions to the session cache.
