855d5046c7 Unwind legacy SSL_PRIVATE_KEY_METHOD hooks.
After much procrastinating, we finally moved Chromium to the new stuff.
We can now delete this. This is a breaking change for
SSL_PRIVATE_KEY_METHOD consumers, but it should be trivial (remove some
unused fields in the struct). I've bumped BORINGSSL_API_VERSION to ease
any multi-sided changes that may be needed.

e7c95d91f8 Run TLS 1.3 tests at all variants and fix bugs.
We were only running a random subset of TLS 1.3 tests with variants and
let a lot of bugs through as a result.

- HelloRetryRequest-EmptyCookie wasn't actually testing what we were
  trying to test.

- The second HelloRetryRequest detection needs tweaks in draft-22.

- The empty HelloRetryRequest logic can't be based on non-empty
  extensions in draft-22.

- We weren't sending ChangeCipherSpec correctly in HRR or testing it
  right.

- Rework how runner reads ChangeCipherSpec by setting a flag which
  affects the next readRecord. This cuts down a lot of cases and works
  correctly if the client didn't send early data. (In that case, we
  don't flush CCS until EndOfEarlyData and runner deadlocks waiting for
  the ChangeCipherSpec to arrive.)

13761f2833 Fix TLSInnerPlaintext limit.
See https://github.com/tlswg/tls13-spec/pull/1083. We misread the
original text spec, but it turns out the original spec text required
senders have version-specific maximum send fragments. The PR fixes this
off-by-one issue. Align with the new spec text uniformly.

This is a wire format change for our existing drafts *only if* records
have padding. We don't currently send padding, so this is fine. Unpadded
records continue to be capped at 2^14 bytes of plaintext (or 2^14+1
bytes of TLSInnerPlaintext structure).

ed84291188 Revert "Pack encrypted handshake messages together."
This reverts commit 75d43b5785. Chatting
with EKR, there is some reason to believe that doing this might cause
more middlebox issues. Since we're still in the middle of working
towards viable deployment in the first place, revert this.

We can experiment with this later. I should have arranged for this to be
controlled more carefully anyway.

75d43b5785 Pack encrypted handshake messages together.
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,
so get this tight from the start.

dd6c2e880f Check early ALPN before offering 0-RTT.
We enforce that servers don't send bogus ALPN values, so consumers may
assume that SSL_get0_alpn_selected won't have anything terribly weird.
To maintain that invariant in the face of folks whose ALPN preferences
change (consider a persisted session cache), we should decline to offer
0-RTT if early_alpn would have been rejected by the check anyway.

a031b61230 Replace open_close_notify with open_app_data.
While a fairly small hook, open_close_notify is pretty weird. It
processes things at the record level and not above. Notably, this will
break if it skips past a TLS 1.3 KeyUpdate.

Instead, it can share the core part of SSL_read/SSL_peek, with slight
tweaks to post-handshake processing. Note this does require some tweaks
to that code. Notably, to retain the current semantics that SSL_shutdown
does not call funny callbacks, we suppress tickets.

40e94701dc Always process handshake records in full.
This removes the last place where non-app-data hooks leave anything
uncomsumed in rrec. (There is still a place where non-app-data hooks see
a non-empty rrec an entrance. read_app_data calls into read_handshake.
That'll be fixed in a later patch in this series.)

This should not change behavior, though some error codes may change due
to some processing happening in a slightly different order.

Since we do this in a few places, this adds a BUF_MEM_append with tests.

81f030b106 Switch OPENSSL_VERSION_NUMBER to 1.1.0.
Although we are derived from 1.0.2, we mimic 1.1.0 in some ways around
our FOO_up_ref functions and opaque libssl types. This causes some
difficulties when porting third-party code as any OPENSSL_VERSION_NUMBER
checks for 1.1.0 APIs we have will be wrong.

Moreover, adding accessors without changing OPENSSL_VERSION_NUMBER can
break external projects. It is common to implement a compatibility
version of an accessor under #ifdef as a static function. This then
conflicts with our headers if we, unlike OpenSSL 1.0.2, have this
function.

This change switches OPENSSL_VERSION_NUMBER to 1.1.0 and atomically adds
enough accessors for software with 1.1.0 support already. The hope is
this will unblock hiding SSL_CTX and SSL_SESSION, which will be
especially useful with C++-ficiation. The cost is we will hit some
growing pains as more 1.1.0 consumers enter the ecosystem and we
converge on the right set of APIs to import from upstream.

It does not remove any 1.0.2 APIs, so we will not require that all
projects support 1.1.0. The exception is APIs which changed in 1.1.0 but
did not change the function signature. Those are breaking changes.
Specifically:

- SSL_CTX_sess_set_get_cb is now const-correct.

- X509_get0_signature is now const-correct.

For C++ consumers only, this change temporarily includes an overload
hack for SSL_CTX_sess_set_get_cb that keeps the old callback working.
This is a workaround for Node not yet supporting OpenSSL 1.1.0.

The version number is set at (the as yet unreleased) 1.1.0g to denote
that this change includes https://github.com/openssl/openssl/pull/4384.

aba057a4e0 Work around a Java client bug when rotating certificates.
The Java client implementation of the 3SHAKE mitigation incorrectly
rejects initial handshakes when all of the following are true:

1. The ClientHello offered a session.
2. The session was successfully resumed previously.
3. The server declines the session.
4. The server sends a certificate with a different SAN list than in the
   previous session.

(Note the 3SHAKE mitigation is to reject certificates changes on
renegotiation, while Java's logic applies to initial handshakes as
well.)

The end result is long-lived Java clients break on some certificate
rotations. Fingerprint Java clients and decline all offered sessions.
This avoids (2) while still introducing new sessions to clear any
existing problematic sessions.

a196ea15af Share all of fuzz/{client,server}.cc into fuzzer.h.
There's a lot of duplicated code between the two. This is in preparation
for adding two more of these fuzzers, this time for DTLS.

This fixes a regression in Conscrypt added by

otherwise attempts to return hs->new_session, but that has been released
at this point.

0a471910b4 Test empty extensions fields are omitted.
For historical reasons, TLS allows ServerHellos (and ClientHellos)
without extensions to omit the extensions fields entirely.
https://github.com/openssl/openssl/pull/4296 reports this is even
necessary for compatibility with extension-less clients. We continue to
do so, but add a test for it anyway.

3969fdf860 Test invalid certificates.
The fuzzer should discover this instantly, but it's a sufficiently
important failure case (don't accidentally drop the certificate on the
floor or anything weird like that) that it's probably worth testing.

OpenSSL's API has a non-fatal "soft fail" mode (can we get rid of
this?), so we should set the flag even if config->verify_fail is true.
