a196ea15af Share all of fuzz/{client,server}.cc into fuzzer.h.
There's a lot of duplicated code between the two. This is in preparation
for adding two more of these fuzzers, this time for DTLS.

0a471910b4 Test empty extensions fields are omitted.
For historical reasons, TLS allows ServerHellos (and ClientHellos)
without extensions to omit the extensions fields entirely.
https://github.com/openssl/openssl/pull/4296 reports this is even
necessary for compatibility with extension-less clients. We continue to
do so, but add a test for it anyway.

5c4271f7cb Don't reauthenticate on renegotiation.
We currently forbid the server certificate from changing on
renegotiation. This means re-verifying the certificate is pointless and
indeed the callback being called again seems to surprise consumers more
than anything else.

Carry over the initial handshake's SCT lists and OCSP responses (don't
enforce they don't change since the server may have, say, picked up new
OCSP responses in the meantime), ignore new ones received on
renegotiation, and don't bother redoing verification.

For our purposes, TLS 1.2 renegotiation is an overcomplicated TLS 1.3
KeyUpdate + post-handshake auth. The server is not allowed to change
identity.

f4ecc84644 Prevent both early data and custom extensions from being accepted.
This loosens the earlier restriction to match Channel ID. Both may be
configured and offered, but the server is obligated to select only one
of them. This aligns with the current tokbind + 0-RTT draft where the
combination is signaled by a separate extension.

e39ac8fb59 Switch BORINGSSL_INTERNAL_CXX_TYPES in favor of subclassing games.
The previous attempt around the 'struct ssl_st' compatibility mess
offended OSS-Fuzz and UBSan because one compilation unit passed a
function pointer with ssl_st* and another called it with
bssl::SSLConnection*.

Linkers don't retain such types, of course, but to silence this alert,
instead make C-visible types be separate from the implementation and
subclass the public type. This does mean we risk polluting the symbol
namespace, but hopefully the compiler is smart enough to inline the
visible struct's constructor and destructor.

86e95b852e Move libssl's internals into the bssl namespace.
This is horrible, but everything else I tried was worse. The goal with
this CL is to take the extern "C" out of ssl/internal.h and move most
symbols to namespace bssl, so we can start using C++ helpers and
destructors without worry.

Complications:

- Public API functions must be extern "C" and match their declaration in
  ssl.h, which is unnamespaced. C++ really does not want you to
  interleave namespaced and unnamespaced things. One can actually write
  a namespaced extern "C" function, but this means, from C++'s
  perspective, the function is namespaced. Trying to namespace the
  public header would worked but ended up too deep a rabbithole.

- Our STACK_OF macros do not work right in namespaces.

- The typedefs for our exposed but opaque types are visible in the
  header files and copied into consuming projects as forward
  declarations. We ultimately want to give SSL a destructor, but
  clobbering an unnamespaced ssl_st::~ssl_st seems bad manners.

- MSVC complains about ambiguous names if one typedefs SSL to bssl::SSL.

This CL opts for:

- ssl/*.cc must begin with #define BORINGSSL_INTERNAL_CXX_TYPES. This
  informs the public headers to create forward declarations which are
  compatible with our namespaces.

- For now, C++-defined type FOO ends up at bssl::FOO with a typedef
  outside. Later I imagine we'll rename many of them.

- Internal functions get namespace bssl, so we stop worrying about
  stomping the tls1_prf symbol. Exported C functions are stuck as they
  are. Rather than try anything weird, bite the bullet and reorder files
  which have a mix of public and private functions. I expect that over
  time, the public functions will become fairly small as we move logic
  to more idiomatic C++.

  Files without any public C functions can just be written normally.

- To avoid MSVC troubles, some bssl types are renamed to CPlusPlusStyle
  in advance of them being made idiomatic C++.

b853f315dd Fix handling of ServerHellos with omitted extensions.
Due to SSL 3.0 legacy, TLS 1.0 through 1.2 allow ClientHello and

than write an empty field. We broke this in
https://boringssl-review.googlesource.com/c/17704/ when we needed to a
second ServerHello parsing path.

Fix this and add some regression tests to explicitly test both the
omitted and empty extensions ClientHello and ServerHello cases.

a502239475 Actually test the TLS 1.3 experimental variant.
Adding it to tlsVersions is sort of pointless when we don't test it.

520e1220bb Implement experimental alternate encoding of TLS 1.3.
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.

d9cbb53562 Fix SSL_version on 0-RTT.
Like other handshake properties, when in 0-RTT on the client,
SSL_version should report the predicted version. This used to work on
accident because of how ssl->version got set in handshake_client.c early
(and that TLS 1.4 does not exist), but we no longer do that.

a1ce85696d Test record splitting at all ciphers.
We were missing AES256 and 3DES. Though this test dates to the old
record-splitting code which was much scarier than the new one.

0fde2eb0e3 Update TLS fuzzer format with prepended settings.
This allows us to fill in holes in our fuzzer coverage, notably client
resumption (and thus early data) and server client certificates. The
corpora are not refreshed yet. This will be done in upcoming changes.

Also add an option for debugging fuzzers. It's very useful to test it on
transcripts and make sure that fuzzer mode successfully makes things
compatible.
