Whether the host has a valid certificate or private key may depend on

negotiating the delegated credential extension (see

JDK 11 shipped with a TLS 1.3 implementation enabled by default.
Unfortunately, that implementation does not work and fails to send the
SNI extension on resumption. See
https://bugs.openjdk.java.net/browse/JDK-8211806.
This means servers which enable TLS 1.3 will see JDK 11 clients work on
the first connection and then fail on all subsequent connections. Add
SSL_set_jdk11_workaround which configures a workaround to fingerprint
JDK 11 and disable TLS 1.3 with the faulty clients.
JDK 11 also implemented the downgrade signal, which means that
connections that trigger the workaround also must not send the downgrade
signal. Unfortunately, the downgrade signal's security properties are
sensitive to the existence of any unmarked TLS 1.2 ServerHello paths. To
salvage this, pick a new random downgrade marker for this scenario and
modify the client to treat it as an alias of the standard one.
Per the link above, JDK 11.0.2 will fix this bug. Hopefully the
workaround can be retired sometime after it is released.

Adds a negative test to make sure that by default we don't verify the

Previously we'd partially attempted the ssl_st / bssl::SSLConnection
subclassing split, but that gets messy when we actually try to add a
destructor, because CRYPTO_EX_DATA's cleanup function needs an ssl_st*,
not a bssl::SSLConnection*. Downcasting is technically undefined at this
point and will likely offend some CFI-like check.
Moreover, it appears that even with today's subclassing split,
New<SSL>() emits symbols like:
W ssl_st*& std::forward<ssl_st*&>(std::remove_reference<ssl_st*&>::type&)
The compiler does not bother emitting them in optimized builds, but it
does suggest we can't really avoid claiming the ssl_st type name at the
symbol level, short of doing reinterpret_casts at all API boundaries.
And, of course, we've already long claimed it at the #include level.
So I've just left this defining directly on ssl_session_st. The cost is
we need to write some silly "bssl::" prefixes in the headers, but so it
goes. In the likely event we change our minds again, we can always
revise this.
