The PACKET should hold a 'const unsigned char*' underneath as well
but the legacy code passes the record buffer around as 'unsigned char*'
(to callbacks, too) so that's a bigger refactor.

Previously TLSProxy would detect a successful handshake once it saw the
server Finished message. This causes problems with abbreviated handshakes,
or if the client fails to process a message from the last server flight.

This change additionally sends some application data and finishes when the
client sends a CloseNotify.

A DTLS client will abort a handshake if the server attempts to renew the
session ticket. This is caused by a state machine discrepancy between DTLS
and TLS discovered during the state machine rewrite work.

The bug can be demonstrated as follows:

Start a DTLS s_server instance:
openssl s_server -dtls

Start a client and obtain a session but no ticket:
openssl s_client -dtls -sess_out session.pem -no_ticket

Now start a client reusing the session, but allow a ticket:
openssl s_client -dtls -sess_in session.pem

The client will abort the handshake.
