1c361b4a39 Add a capability for TLSProxy to wait for a session before killing s_client
TLSProxy normally fires off s_client, which creates a connection to the
server. TLSProxy also pipes some data to send to the process and s_client
automatically exits when the pipe hits eof. Unfortunately this means that
it sends the data and closes before it has processed the NewSessionTicket
returned from the server in TLSv1.3. This commits adds an option for
s_client to stay loaded until the sesion has been processed. A side effect
of this is that s_client never sends a close_notify in this mode, so we
count success as seeing that data has been transferred.

79d8c16785 Extend ServerKeyExchange parsing to work with a signature
Previously SKE in TLSProxy only knew about one anonymous ciphersuite so
there was never a signature. Extend that to include a ciphersuite that is
not anonymous. This also fixes a bug where the existing SKE processing was
checking against the wrong anon ciphersuite value. This has a knock on
impact on the sslskewith0p test. The bug meant the test was working...but
entirely by accident!

397f4f7876 Add a test to check the EC point formats extension appears when we expect
The previous commit fixed a bug where the EC point formats extensions did
not appear in the ServerHello. This should have been caught by
70-test_sslmessages but that test never tries an EC ciphersuite. This
updates the test to do that.

70af3d8ed7 Avoid repeatedly scanning the list of extensions
Because extensions were keyed by type which is sparse, we were continually
scanning the list to find the one we wanted. The way we stored them also
had the side effect that we were running initialisers/finalisers in a
different oder to the parsers. In this commit we change things so that we
instead key on an index value for each extension.

8523288e6d Test CBC mode padding.
This is a regression test for
https://github.com/openssl/openssl/pull/1431. It tests a
maximally-padded record with each possible invalid offset.

This required fixing a bug in Message.pm where the client sending a
fatal alert followed by close_notify was still treated as success.

aa474d1fb1 TLS: reject duplicate extensions
Adapted from BoringSSL. Added a test.

The extension parsing code is already attempting to already handle this for
some individual extensions, but it is doing so inconsistently. Duplicate
efforts in individual extension parsing will be cleaned up in a follow-up.

8af538e5c5 Fix TLSProxy end of test detection
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.

631c120633 Add a libssl test harness
This commit provides a set of perl modules that support the testing of
libssl. The test harness operates as a man-in-the-middle proxy between
s_server and s_client. Both s_server and s_client must be started using the
"-testmode" option which loads the new OSSLTEST engine.

The test harness enables scripts to be written that can examine the packets
sent during a handshake, as well as (potentially) modifying them so that
otherwise illegal handshake messages can be sent.
