09bd58d1f1 flipped a condition. Doing that
memset in the DTLS case breaks retransmits across a CCS and fails to memset in
the TLS case.
Strangely, it didn't break any tests, but I think that's a function of us
lacking renego tests. The sequence number doesn't seem to be used in the
initial handshake for TLS, so it stayed at zero. After a renego, that codepath
is relevant.

To align with what Chrome sends on NSS, remove all 3DES cipher suites except
RSA_WITH_3DES_EDE_CBC_SHA. This avoids having to order a PFS 3DES cipher
against a non-PFS 3DES cipher.
Remove the strength sort which wanted place AES_256_CBC ahead of AES_128_GCM
and is not especially useful (everything under 128 is either 3DES or DES).
Instead, explicitly order all the bulk ciphers. Continue to prefer PFS over
non-PFS and ECDHE over DHE.
This gives the following order in Chromium. We can probably prune it a bit

Rather than switching the order of the ServerHello and HelloVerifyRequest

Fix the dtls1_stop_timer call in these states to consistently hit the end of a

buffer until the entire next flight is received. That said, OpenSSL doesn't
appear to implement the part where, on receipt of the previous peer flight, the
buffered flight is retransmitted. (With the exception of a SSL3_MT_FINISHED
special-case in dtls1_read_bytes.) So if the peer is also OpenSSL, this doesn't
do anything.

Of the remaining implementations left, ssl3_, dtls1_, and ssl23_, dtls1_ is
redundant and can be folded into ssl3_. ssl23_ actually isn't; it sets 5
minutes rather than 2 hours. Two hours seems to be what everything else uses
and seems a saner default. Most consumers seem to override it anyway
(SSL_CTX_set_timeout). But it is a behavior change.
The method is called at two points:
- SSL_get_default_timeout
- SSL_CTX_new
Incidentally, the latter call actually makes the former never called internally
and the value it returns a lie. SSL_get_default_timeout returns the default
timeout of the /current/ method, but in ssl_get_new_session, the timeout is
shadowed by session_timeout on the context. That is initialized when
SSL_CTX_new is called. So, unless you go out of your way to
SSL_CTX_set_timeout(0), it always overrides. (And it actually used to a
difference because, for SSL23, the SSL_CTX's method is SSL23, but, when session
creation happens, the SSL's method is the version-specific one.)

In particular, it assumes a reliable, in-order channel. And it requires that
the peer send handshake fragments in order. Retransmit and whatnot are not
implemented. The peer under test will be expected to handle a lossy channel,
but all loss in the channel will be controlled. MAC errors, etc., are fatal.

even older SSL_OP_NON_EXPORT_FIRST option (see upstream's

Split it into three states and move V2ClientHello parsing into its own

parse.
This fixes a minor bug where, if the SSL_accept call in ssl23_get_client_hello

extra time.
It also unbreaks the invariant between s->packet, s->packet_length,

was of no consequence because the first ssl3_read_n call passes extend = 0
