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.

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.

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.

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.

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.

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.

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.
