f182ee1bba Always release init_buf after the handshake.
Post-handshake retransmit in DTLS no longer needs that scratch space.

429fdc0d3d Simplify ssl3_send_cert_verify's async logic.
The only thing we've written before the signature is the hash. We can just
choose it anew. This is along the way to getting init_buf out of the handshake
output side. (init_buf is kind of a mess since it doesn't integrate nicely with
a top-level CBB. Some of the logic hasn't been converted to CBB because they're
interspersed with a BUF_MEM_grow.)

f0ee907942 Remove the 'ssl_' prefix on most SSL_PROTOCOL_METHOD hooks.
It doesn't really convey anything useful. Leave ssl_get_message alone for now
since it's called everywhere in the handshake and I'm about to tweak it
further.

5744ca6bff Fold cert_req into cert_request.
That both exist with nearly the same name is unfortunate. This also does away
with cert_req being unnecessarily tri-state.

47749a6a29 Make the handshake state machines more linear.
TLS 1.2 has a long series of optional messages within a flight. We really
should send and process these synchronously. In the meantime, the 'skip'
pattern is probably the best we can get away with. Otherwise we have too many
state transitions to think about. (The business with CCS, NPN, and ChannelID is
particularly a headache. Session tickets aren't great either.)

bde00394f0 Stop messing with ssl->version before sending protocol_version.
This is the only codepath where ssl->version can get a garbage value, which is
a little concerning. Since, in all these cases, the peer is failing to connect
and speaks so low a version we don't even accept it anymore, there is probably
not much value in letting them distinguish protocol_version from a record-layer
version number mismatch, where enforced (which will give a version-related
error anyway).

Should we get a decode_error or so just before version negotiation, we'd have
this behavior already.

1fd39d84cf Add TLS 1.3 record layer to go implementation.
This implements the cipher suite constraints in "fake TLS 1.3". It also makes
bssl_shim and runner enable it by default so we can start adding MaxVersion:
VersionTLS12 markers to tests as 1.2 vs. 1.3 differences begin to take effect.
