Update-Note: Now that tls13_experiment2 is gone, the server should remove the set_tls13_variant call. To avoid further churn, we'll make the server default for future variants to be what we'd like to deploy.

(Configuring any TLS 1.3 variants on the server enables all variants,

These are common between TLS and DTLS so should not have the ssl3_
prefix. (TLS-only stuff should really have a tls_ prefix, but we still
have a lot of that one.)
This also fixes a stray reference to ssl3_send_client_key_exchange..

Use SSL_SESSION_get_digest instead of the lower level function where
applicable. Also, remove the failure case (Ivan Maidanski points out in
https://android-review.googlesource.com/c/337852/1/src/ssl/t1_enc.c that
this unreachable codepath is a memory leak) by passing in an SSL_CIPHER
to make it more locally obvious that other values are impossible.

Rather than init_msg/init_num, there is a get_message function which
either returns success or try again. This function does not advance the
current message (see the previous preparatory change). It only completes
the current one if necessary.
Being idempotent means it may be freely placed at the top of states
which otherwise have other asychronous operations. It also eases
converting the TLS 1.2 state machine. See
https://docs.google.com/a/google.com/document/d/11n7LHsT3GwE34LAJIe3EFs4165TI4UR_3CqiM9LJVpI/edit?usp=sharing
for details.
The read_message hook (later to be replaced by something which doesn't
depend on BIO) intentionally does not finish the handshake, only "makes
progress". A follow-up change will align both TLS and DTLS on consuming
one handshake record and always consuming the entire record (so init_buf
may contain trailing data). In a few places I've gone ahead and
accounted for that case because it was more natural to do so.
This change also removes a couple pointers of redundant state from every
socket.

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.

This adds several utilities as replacements for new and delete and makes
bssl::UniquePtr work with our private types.
Later work can convert more incrementally. I did this one more
aggressively to see how it'd work. Unfortunately, in doing so, I needed
to remove the NULL SSL_AEAD_CTX "method" receiver trick to appease
clang. The null cipher is now represented by a concrete SSL_AEAD_CTX.
The long-lived references to SSL_AEAD_CTX are not yet in types with
constructors, so they still bare Delete rather than UniquePtr for now.
Though this does mean we may be able to move the sequence number into
SSLAEADContext later which is one less object for DTLS to carry around.

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++.
