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.

For now, this is the laziest conversion possible. The intent is to just
get the build setup ready so that we can get everything working in our
consumers. The intended end state is:
- The standalone build produces three test targets, one per library:
{crypto,ssl,decrepit}_tests.
- Each FOO_test is made up of:
FOO/**/*_test.cc
crypto/test/gtest_main.cc
test_support
- generate_build_files.py emits variables crypto_test_sources and
ssl_test_sources. These variables are populated with FindCFiles,
looking for *_test.cc.
- The consuming file assembles those variables into the two test targets
(plus decrepit) from there. This avoids having generate_build_files.py
emit actual build rules.
- Our standalone builders, Chromium, and Android just run the top-level
test targets using whatever GTest-based reporting story they have.
In transition, we start by converting one of two tests in each library
to populate the three test targets. Those are added to all_tests.json
and all_tests.go hacked to handle them transparently. This keeps our
standalone builder working.
generate_build_files.py, to start with, populates the new source lists
manually and subtracts them out of the old machinery. We emit both for
the time being. When this change rolls in, we'll write all the build
glue needed to build the GTest-based tests and add it to consumers'
continuous builders.
Next, we'll subsume a file-based test and get the consumers working with
that. (I.e. make sure the GTest targets can depend on a data file.)
Once that's all done, we'll be sure all this will work. At that point,
we start subsuming the remaining tests into the GTest targets and,
asynchronously, rewriting tests to use GTest properly rather than
cursory conversion here.
When all non-GTest tests are gone, the old generate_build_files.py hooks
will be removed, consumers updated to not depend on them, and standalone
builders converted to not rely on all_tests.go, which can then be
removed. (Unless bits end up being needed as a malloc test driver. I'm
thinking we'll want to do something with --gtest_filter.)
As part of this CL, I've bumped the CMake requirements (for
target_include_directories) and added a few suppressions for warnings
that GTest doesn't pass.

The new curve is not enabled by default.
As EC_GROUP/EC_POINT is a bit too complex for X25519, this introduces an
SSL_ECDH_METHOD abstraction which wraps just the raw ECDH operation. It
also tidies up some of the curve code which kept converting back and
force between NIDs and curve IDs. Now everything transits as curve IDs
except for API entry points (SSL_set1_curves) which take NIDs. Those
convert immediately and act on curve IDs from then on.
Note that, like the Go implementation, this slightly tweaks the order of
operations. The client sees the server public key before sending its
own. To keep the abstraction simple, SSL_ECDH_METHOD expects to
generate a keypair before consuming the peer's public key. Instead, the
client handshake stashes the serialized peer public value and defers
parsing it until it comes time to send ClientKeyExchange. (This is
analogous to what it was doing before where it stashed the parsed peer
public value instead.)
It still uses TLS 1.2 terminology everywhere, but this abstraction should also
be compatible with TLS 1.3 which unifies (EC)DH-style key exchanges.
(Accordingly, this abstraction intentionally does not handle parsing the
ClientKeyExchange/ServerKeyExchange framing or attempt to handle asynchronous
plain RSA or the authentication bits.)

It's very annoying having to remember the right incant every time I want
to switch around between my build, build-release, build-asan, etc.,
output directories.
Unfortunately, this target is pretty unfriendly without CMake 3.2+ (and
Ninja 1.5+). This combination gives a USES_TERMINAL flag to
add_custom_target which uses Ninja's "console" pool, otherwise the
output buffering gets in the way. Ubuntu LTS is still on an older CMake,
so do a version check in the meantime.
CMake also has its own test mechanism (CTest), but this doesn't use it.
It seems to prefer knowing what all the tests are and then tries to do
its own output management and parallelizing and such. We already have
our own runners. all_tests.go could actually be converted tidily, but
generate_build_files.py also needs to read it, and runner.go has very
specific needs.
Naming the target ninja -C build test would be nice, but CTest squats
that name and CMake grumps when you use a reserved name, so I've gone
with run_tests.

This begins decoupling the transport from the SSL state machine. The buffering
logic is hidden behind an opaque API. Fields like ssl->packet and
ssl->packet_length are gone.
ssl3_get_record and dtls1_get_record now call low-level tls_open_record and
dtls_open_record functions that unpack a single record independent of who owns
the buffer. Both may be called in-place. This removes ssl->rstate which was
redundant with the buffer length.
Future work will push the buffer up the stack until it is above the handshake.
Then we can expose SSL_open and SSL_seal APIs which act like *_open_record but
return a slightly larger enum due to other events being possible. Likewise the
handshake state machine will be detached from its buffer. The existing
SSL_read, SSL_write, etc., APIs will be implemented on top of SSL_open, etc.,
combined with ssl_read_buffer_* and ssl_write_buffer_*. (Which is why
ssl_read_buffer_extend still tries to abstract between TLS's and DTLS's fairly
different needs.)
The new buffering logic does not support read-ahead (removed previously) since
it lacks a memmove on ssl_read_buffer_discard for TLS, but this could be added
if desired. The old buffering logic wasn't quite right anyway; it tried to
avoid the memmove in some cases and could get stuck too far into the buffer and
not accept records. (The only time the memmove is optional is in DTLS or if
enough of the record header is available to know that the entire next record
would fit in the buffer.)
The new logic also now actually decrypts the ciphertext in-place again, rather
than almost in-place when there's an explicit nonce/IV. (That accidentally
switched in https://boringssl-review.googlesource.com/#/c/4792/; see
