This does not affect TLS 1.2 (beyond Channel ID or NPN) but, in TLS 1.3,
we send several encrypted handshake messages in a row. For the server,
this means 66 wasted bytes in TLS 1.3. Since OpenSSL has otherwise used
one record per message since the beginning and unencrypted overhead is
less interesting, leave that behavior as-is for the time being. (This
isn't the most pressing use of the breakage budget.) But TLS 1.3 is new,

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.

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.

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

The long-lived references to SSL_AEAD_CTX are not yet in types with

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++.
