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.

Once passed to the outside world, an SSL_SESSION is immutable. It is not
thread-safe to set not_resumable. In most cases, the session is already
expired anyway. In other cases, making all this remove session be unlink rather than
destroy is sound and consistent with how we treat sessions elsewhere.
In particular, SSL_CTX_free calls SSL_CTX_flush_sessions(0), and
bulk-invalidating everything like this is interfering with some
follow-up changes to improve the fuzzer.

This is in preparation for upcoming experiments which will require
supporting multiple experimental versions of TLS 1.3 with, on the
server, the ability to enable multiple variants at once. This means the
version <-> wire bijection no longer exists, even when limiting to a
single SSL*. Thus version_to_wire is removed and instead we treat the
wire version as the canonical version value.
There is a mapping from valid wire versions to protocol versions which
describe the high-level handshake protocol in use. This mapping is not
injective, so uses of version_from_wire are rewritten differently.
All the version-munging logic is moved to ssl_versions.c with a master
preference list of all TLS and DTLS versions. The legacy version
negotiation is converted to the new scheme. The version lists and
negotiation are driven by the preference lists and a
ssl_supports_version API.
To simplify the mess around SSL_SESSION and versions, version_from_wire
is now DTLS/TLS-agnostic, with any filtering being done by
ssl_supports_version. This is screwy but allows parsing SSL_SESSIONs to
sanity-check it and reject all bogus versions in SSL_SESSION. This
reduces a mess of error cases.
As part of this, the weird logic where ssl->version is set early when
sending the ClientHello is removed. The one place where we were relying
on this behavior is tweaked to query hs->max_version instead.

Like the write half, rather than allocating the maximum size needed and
relying on the malloc implementation to pool this sanely, allocate the
size the TLS record-layer code believes it needs.
As currently arranged, this will cause us to alternate from a small
allocation (for the record header) and then an allocation sized to the
record itself. Windows is reportedly bad at pooling large allocations,
so, *if the server sends us smaller records*, this will avoid hitting
the problem cases.
If the server sends us size 16k records, the maximum allowed by ther
protocol, we simply must buffer up to that amount and will continue to
allocate similar sizes as before (although slightly smaller; this CL
also fixes small double-counting we did on the allocation sizes).
Separately, we'll gather some metrics in Chromium to see what common
record sizes are to determine if this optimization is sufficient. This
is intended as an easy optimization we can do now, in advance of ongoing
work to fix the extra layer of buffering between Chromium and BoringSSL
with an in-place decrypt API.
