With the current mechanism, old cipher strings that used to work in 1.1.0,
may inadvertently disable all TLSv1.3 ciphersuites causing connections to
fail. This is confusing for users.
In reality TLSv1.3 are quite different to older ciphers. They are much
simpler and there are only a small number of them so, arguably, they don't
need the same level of control that the older ciphers have.
This change splits the configuration of TLSv1.3 ciphers from older ones.
By default the TLSv1.3 ciphers are on, so you cannot inadvertently disable
them through your existing config.

The previous commits added sanity checks for where the max enabled protocol
version does not have any configured ciphersuites. We should check that we
fail in those circumstances.

Also we disable TLS1.3 by default (use enable-tls1_3 to re-enable). This is
because this is a WIP and will not be interoperable with any other TLS1.3
implementation.
Finally, we fix some tests that started failing when TLS1.3 was disabled by
default.

Includes addition of the various options to s_server/s_client. Also adds
one of the new TLS1.3 ciphersuites.
This isn't "real" TLS1.3!! It's identical to TLS1.2 apart from the protocol
and the ciphersuite...and the ciphersuite is just a renamed TLS1.2 one (not
a "real" TLS1.3 ciphersuite).

Move custom server and client options from the test dictionary to an
"extra" section of each server/client. Rename test expectations to say
"Expected".
This is a big but straightforward change. Primarily, this allows us to
specify multiple server and client contexts without redefining the
custom options for each of them. For example, instead of
"ServerNPNProtocols", "Server2NPNProtocols", "ResumeServerNPNProtocols",
we now have, "NPNProtocols".
This simplifies writing resumption and SNI tests. The first application
will be resumption tests for NPN and ALPN.
Regrouping the options also makes it clearer which options apply to the
server, which apply to the client, which configure the test, and which
are test expectations.

Add tests for resuming with a different client version.
This happens in reality when clients persist sessions on disk through

Systematically test every server-side version downgrade or upgrade.
Client version upgrade or downgrade could be tested analogously but will
be done in a later change.
