8fc2dc07d8 Put SCTs and OCSP responses in CRYPTO_BUFFERs.
They both can be moderately large. This should hopefully relieve a little
memory pressure from both connections to hosts which serve SCTs and
TLS 1.3's single-use tickets.

68a0b1b112 Remove RFC 5114 groups.
These groups are terrible, we got the function wrong (unused ENGINE
parameter does not match upstream), and the functions are unused. Unwind
them. This change doesn't unwind the X9.42 Diffie-Hellman machinery, so
the checks are still present and tested.

(We can probably get rid of the X9.42 machinery too, but it is reachable
from DSA_dup_DH.  That's only used by wpa_supplicant and, if that code
ever ran, it'd be ignored because we don't support DHE in TLS. I've left
it alone for the time being.)

7934f08b26 Replace init_msg/init_num with a get_message hook.
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.

af2b1e8210 C++ headers should be more aggressively wrapped in extern "C++".
This is kind of a mess. Some projects will wrap our public headers in
extern "C", so we use extern "C++" around our C++ APIs. However this
needs to be done when including C++ standard library headers too since
they don't always, themselves, guard against being wrapped in extern
"C".

ec783839be Make ranged for loops work with STACK_OF(T).
My original plan here was to make STACK_OF(T) expand to a template so
the inner type were extractable. Unfortunately, we cannot sanely make
STACK_OF(T) expand to a different type in C and C++ even across
compilation units because UBSan sometimes explodes. This is nuts, but so
it goes.

Instead, use StackTraits to extract the STACK_OF(T) parameters and
define an iterator type.

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.

cfc11c2320 C++-ify SSL_AEAD_CTX.
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.

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++.

This also serves as a certificate verification callback for
CRYPTO_BUFFER-based consumers. Remove the silly
SSL_CTX_i_promise_to_verify_certs_after_the_handshake placeholder.

7e9e06a739 Use OPENSSL_UNUSED in OPENSSL_COMPILE_ASSERT.
This would also have fixed the Windows clang issues. Those kicked in
because Windows clang defines __clang__ and not __GNUC__, but
OPENSSL_UNUSED accounts for this. It's also shorter.

Local experiments were not able to replicate the claims in the PR, but
implement this anyway for comparison purposes.

e8703a3708 Switch a number of files to C++.
http://i1.kym-cdn.com/photos/images/original/000/242/631/382.gif

In the first step, switch C files to C++ individually, keeping
everything in internal.h C-compatible. We'll make minimal changes needed
to get things compiling (notably a lot of goto errs will need to turn to
bssl::UniquePtr right away), but more aggressive changes will happen in
later steps.

(To avoid a rebase, I'm intentionally avoiding files that would conflict
with CLs in flight right now.)

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.

6fff386492 Support standard RFC cipher suite names alongside OpenSSL ones.
Both Conscrypt and Netty have a lot of logic to map between the two
kinds of names. WebRTC needed an SSL_CIPHER_get_rfc_name for something.
Just have both in the library. Also deprecate SSL_CIPHER_get_rfc_name
in favor of SSL_CIPHER_standard_name, which matches upstream if built
with enable-ssl-trace. And, unlike SSL_CIPHER_get_rfc_name, this does
not require dealing with the malloc.

(Strangely this decreases bssl's binary size, even though we're carrying
more strings around. It seems the old SSL_CIPHER_get_rfc_name was
somewhat large in comparison. Regardless, a consumer that disliked 30
short strings probably also disliked the OpenSSL names. That would be
better solved by opaquifying SSL_CIPHER and adding a less stringy API
for configuring cipher lists. That's something we can explore later if
needed.)

I also made the command-line tool print out the standard names since
they're more standard. May as well push folks towards those going
forward.
