Run against openssl s_client and openssl s_server. This seems to work for a
start, although it may need to become cleverer to stress more of BoringSSL's
implementation for test purposes.
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.

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.

are allowed, meaning that an attacker could consume ~180MB per DTLS

When the write size was exactly SSL3_RT_MAX_PLAIN_LENGTH+1 and record
splitting is needed, an extra byte would be added to the max size of the
message to be written. This would cause the requested size to not exceed
the max. If the SSL_WANT_WRITE error were returned, the next packet
would not get the extra byte added to the max packet size since
record_split_done is set. Since a different set of arguments
(SSL3_RT_MAX_PLAIN_LENGTH+1 vs SSL3_RT_MAX_PLAIN_LENGTH) would be passed
to do_ssl3_write, it would return an "SSL3_WRITE_PENDING:bad write
retry" error.
To avoid a failure in the opposite direction, the max variable increment
is removed as well. This can happen when SSL_MODE_ENABLE_PARTIAL_WRITE
is not enabled and the call to ssl3_write_bytes contains, e.g., a buffer
of 2*SSL3_RT_MAX_PLAIN_LENGTH, where the first call into do_ssl3_write
succeeds writing the first SSL3_RT_MAX_PLAIN_LENGTH bytes, but writing
the second SSL3_RT_MAX_PLAIN_LENGTH bytes fails. This means the first
time the the second section of SSL3_RT_MAX_PLAIN_LENGTH bytes has called
do_ssl3_write with "max" bytes, but next call to ssl3_write_bytes in
turn calls into do_ssl3_write with "max+1" bytes.
