d1e3ce1fb0 Rename ssl3_send_alert and ssl3_protocol_version.
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..

27e377ec65 Fix miscellaneous clang-tidy warnings.
There are still a ton of them, almost exclusively complaints that
function declaration and definitions have different parameter names. I
just fixed a few randomly.

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.

e664a534af Return null from SSL_get0_peer_certificates if unauthenticated.
SSL_get0_peer_certificates is documented to return NULL if the peer was
anonymous, but it actually returns a non-NULL empty list (except in SSL
3.0 where the Certificate message and thus ssl_parse_cert_chain is
skipped).

Make the implementation match the documentation.

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++.
