Although this is forbidden by all three(!) relevant specifications,
there seem to be multiple server implementations in the wild that
send it. Since we didn't check for unexpected extensions in any
given message type until TLS 1.3 support was added, our previous
behavior was to silently accept these extensions and pass them over
to the custom extension callback (if any). In order to avoid
regression of functionality, relax the check for "extension in
unexpected context" for this specific case, but leave the protocol
enforcment mechanism unchanged for other extensions and in other
extension contexts.
Leave a detailed comment to indicate what is going on.

We don't keep track of the number of bytes written between in the
SSL_write_ex() call and the subsequent flush. If the flush needs to be
retried then we will have forgotten how many bytes actually got written.
The simplest solution is to just disable it for this scenario.

We'd like the first bit of early_data and the ClientHello to go in the
same TCP packet if at all possible to enable things like TCP Fast Open.
Also, if you're only going to send one block of early data then you also
don't need to worry about TCP_NODELAY.

A third shared DRBG is added, the so called master DRBG. Its sole purpose
is to reseed the two other shared DRBGs, the public and the private DRBG.
The randomness for the master DRBG is either pulled from the os entropy
sources, or added by the application using the RAND_add() call.
The master DRBG reseeds itself automatically after a given number of generate
requests, but can also be reseeded using RAND_seed() or RAND_add().
A reseeding of the master DRBG is automatically propagated to the public
and private DRBG. This construction fixes the problem, that up to now
the randomness provided by RAND_add() was added only to the public and
not to the private DRBG.

Normally we flush immediately after writing the ClientHello. However if
we are going to write a CCS immediately because we've got early_data to
come, then we should move the flush until after the CCS.

The new ServerHello format is essentially now the same as the old TLSv1.2
one, but it must additionally include supported_versions. The version
field is fixed at TLSv1.2, and the version negotiation happens solely via
supported_versions.

IF OPENSSL_init_ssl() is called with the option flag
OPENSSL_INIT_LOAD_CONFIG, any SSL config will be handled wrongly
(i.e. there will be an attempt to load libssl_conf.so or whatever
corresponds to that on non-Unix platforms). Therefore, at least
SSL_add_ssl_module() MUST be called before OPENSSL_init_crypto() is
called. The base ssl init does that, plus adds all kinds of ciphers
and digests, which is harmless.

The check_fatal macro is supposed to only be called if we are already
expecting to be in the fatal state. The macro asserts that we are and
puts us into the fatal state if not.
This issue combined with the problem fixed in the previous commit meant
that the fuzzer detected a crash at a point in the processing when we
should have already been in the fatal state.
