I found no users of this. We can restore it if needbe, but I don't expect
anyone to find it useful in its current form. The API is suspect for the same
reasons DTLSv1_listen was. An SSL object is stateful and assumes you already
have the endpoint separated out.
If we ever need it, server-side HelloVerifyRequest and DTLSv1_listen should be
implemented by a separate stateless listener that statelessly handles
cookieless ClientHello + HelloVerifyRequest. Once a ClientHello with a valid
cookie comes in, it sets up a stateful SSL object and passes control along to
that.

SSL_ST_BEFORE is never standalone. As of upstream's
413c4f45ed0508d2242638696b7665f499d68265, SSL_ST_BEFORE is only ever set paired
with SSL_ST_ACCEPT or SSL_ST_CONNECT.
Conversely, SSL_ST_OK is never paired with SSL_ST_ACCEPT or SSL_ST_CONNECT. As
far as I can tell, this combination has never been possible.

Get all this stuff out of the way.
- OPENSSL_NO_MD5
- OPENSSL_NO_SHA
- OPENSSL_NO_EC
- OPENSSL_NO_ECDSA
- OPENSSL_NO_ECDH
- OPENSSL_NO_NEXTPROTONEG
- OPENSSL_NO_DH
- OPENSSL_NO_SSL3
- OPENSSL_NO_RC4
- OPENSSL_NO_RSA
Also manually removed a couple instances of OPENSSL_NO_DSA that seemed to be
confused anyway. Did some minor manual cleanup. (Removed a few now-pointless
'if (0)'s.)

ssl23_get_client_hello has lots of remnants of SSLv2 support and remnants of an
even older SSL_OP_NON_EXPORT_FIRST option (see upstream's
d92f0bb6e9ed94ac0c3aa0c939f2565f2ed95935) which complicates the logic.
Split it into three states and move V2ClientHello parsing into its own
function. Port it to CBS and CBB to give bounds checks on the V2ClientHello
parse.
This fixes a minor bug where, if the SSL_accept call in ssl23_get_client_hello
failed, cb would not be NULL'd and SSL_CB_ACCEPT_LOOP would get reported an
extra time.
It also unbreaks the invariant between s->packet, s->packet_length,
s->s3->rbuf.buf, and s->s3->rbuf.offset at the point the switch, although this
was of no consequence because the first ssl3_read_n call passes extend = 0
which resets s->packet and s->packet_length.
It also makes us tolerant to major version bumps in the ClientHello. Add tests
for TLS tolerance of both minor and major version bumps as well as the HTTP
request error codes.

Introduce a CR_CHANGE state just before entering CR_FINISHED_A. This replaces
the CCS_OK in the CR_FINISHED_A/CR_FINISHED_B case which otherwise would get
applied after partial reads of Finished. The other CCS_OK settings are
redundant with this one.
The copy in tls_secret_session_cb codepath is made unnecessary with
9eaeef81fa.
The copy in the normal session resumption case is unnecessary with
6444287806. Before that commit, OpenSSL would
potentially read Finished a state early. Now that we are strict (and get the
book-keeping correct) for expecting the NewSessionTicket message it too is
redundant.
Of particular note is the one after ssl3_send_finished. That was added in
response to upstream's PR#3400. I've reproduced the bug and concluded it was
actually a bug around expecting a NewSessionTicket message. That has been fixed
properly in 6444287806 by resetting
tlsext_expect_ticket on renegotiations.

Rename SSL3_ST_SR_POST_CLIENT_CERT to SSL3_ST_SR_CHANGE and have this be the
point at which CCS_OK is set. The copy before ssl3_get_finished is redundant as
we never transition to SR_FINISHED directly.
