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.

Rather than printing the SSL_ERROR_* constants, print the actual error.
This should be a bit more understandable. Debugging this also uncovered
some other issues on Windows:
- We were mixing up C runtime and Winsock errors, which are separate in
Windows.
- The thread local implementation interferes with WSAGetLastError due to
a quirk of TlsGetValue. This could affect other Windows consumers.
(Chromium uses a custom BIO, so it isn't affected.)
- SocketSetNonBlocking also interferes with WSAGetLastError.
- Listen for FD_CLOSE along with FD_READ. Connection close does not
signal FD_READ. (The select loop only barely works on Windows anyway
due to issues with stdin and line buffering, but if we take stdin out
of the equation, FD_CLOSE can be tested.)

TLS 1.3 deployment is currently blocked by buggy middleboxes
throughout the ecosystem. As an experiment to better understand these bugs
and the problems they are causing, implement TLS 1.3 variants with
alternate encodings. These are still the same protocol, only encoded
slightly differently. We will use what we learn from these experiments to
guide the TLS 1.3 deployment strategy and proposals to the IETF, if any.
These experiments only target the basic 1-RTT TLS 1.3 handshake. Based on
what we learn from this experiment, we may try future variations to
explore 0-RTT and HelloRetryRequest.
When enabled, the server supports all TLS 1.3 variants while the client
is configured to use a particular variant.

The new APIs are SSL_CTX_set_strict_cipher_list() and
SSL_set_strict_cipher_list(). They have two motivations:
First, typos in cipher lists can go undetected for a long time, and
can have surprising consequences when silently ignored.
Second, there is a tendency to use superstition in the construction of
cipher lists, for example by "turning off" things that do not actually
exist. This leads to the corrosive belief that DEFAULT and ALL ought
not to be trusted. This belief is false.

This is in preparation for using the supported_versions extension to
experiment with draft TLS 1.3 versions, since we don't wish to restore
the fallback. With versions begin opaque values, we will want
version_from_wire to reject unknown values, not attempt to preserve
order in some way.
This means ClientHello.version processing needs to be separate code.
That's just written out fully in negotiate_version now. It also means
SSL_set_{min,max}_version will notice invalid inputs which aligns us
better with upstream's versions of those APIs.
This CL doesn't replace ssl->version with an internal-representation
version, though follow work should do it once a couple of changes land

Thus this change moves some of the template code to base.h and puts it
all in a |bssl| namespace to prepare for scattering these types into
their respective headers. In order that all the existing test code be
able to access these types, it's all moved into the same namespace.
