In 1.1.0 changing the ciphersuite during a renegotiation can result in
a crash leading to a DoS attack. In master this does not occur with TLS
(instead you get an internal error, which is still wrong but not a security
issue) - but the problem still exists in the DTLS code.
The problem is caused by changing the flag indicating whether to use ETM
or not immediately on negotiation of ETM, rather than at CCS. Therefore,
during a renegotiation, if the ETM state is changing (usually due to a
change of ciphersuite), then an error/crash will occur.
Due to the fact that there are separate CCS messages for read and write
we actually now need two flags to determine whether to use ETM or not.

Previously counting the number of tests in checkhandshake.pm took an
initial guess and then modified it based on various known special
cases. That is becoming increasingly untenable, so this changes it to
properly calculate the number of tests we expect to run.

test/recipes/40-test_rehash.t uses test files from certs/demo, which
doesn't exist any longer. Have it use PEM files from test/ instead.
Because rehash wants only one certificate or CRL per file, we must
also filter those PEM files to produce test files with a single object
each.

If s->s3->tmp.new_cipher is NULL then a crash can occur. This can happen
if an alert gets sent after version negotiation (i.e. we have selected
TLSv1.3 and ended up in tls13_enc), but before a ciphersuite has been
selected.

Idea is to keep it last for all eternity, so that if you find yourself

The default behavior, as added to EVP, is to use 16-byte output and

There is an EVP_PKEY_CTRL that can control the output size.

In TLSv1.3 the connection will be created before the session is
established. In OpenSSL we send the NewSessionTicket message immediately
after the client finished has been received. Therefore we change
create_ssl_connection() to attempt a read of application data after the
handshake has completed. We expect this to fail but it will force the
reading of the NewSessionTicket and the session to be set up.
