This serves two purposes:
1. Make sure we don't accidentally write "throw" or "catch" in our code.
2. If a C project statically links to our libssl.a, they'll use gcc
rather than g++ as the linker which does not pull in the C++ runtime.
-fno-exceptions cuts out the C++ runtime dependency. (Though we will
need to give up on this should we attempt to allow a runtime
dependency in the future.)

The former is defined by the kernel and is a straightforward number. The
latter is defined by glibc as:
#define SYS_getrandom __NR_getrandom
which does not work when kernel headers are older than glibc headers.
Instead, use the kernel values.

Clang for Windows does not like OPENSSL_COMPILE_ASSERT inside a function

But libssl is now C++ and assumes a C++11-capable compiler. Use real

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.)

This isn't all of our pointer games by far, but for any code which
doesn't run on armv6, memcpy and pointer cast compile to the same code.
For code with does care about armv6 (do we care?), it'll need a bit more
work. armv6 makes memcpy into a function call.
Ironically, the one platform where C needs its alignment rules is the
one platform that makes it hard to honor C's alignment rules.

This tag doesn't actually do anything, except cause UBSan to point out
that malloc doesn't align that tightly. malloc does, however, appear to
align up to 16-bytes, which is the actual alignment requirement of that
code. So just replace 64 with 16.
When we're juggling less things, it'd be nice to see what toolchain
support for the various aligned allocators looks like. Or maybe someday
we can use C++ new which one hopes is smart enough to deal with all
this.

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.
