While IO::Socket::IP is a core perl module (since Perl v5.19.8, or so
says corelist), IO::Socket::INET6 has been around longer, is said to
be more widely deployed, and most importantly, seems to have less bugs
hitting us. We therefore prefer IO::Socket::INET6, and only fall back
to IO::Socket::IP if the former doesn't exist on the local system.

When connecting to "localhost" the Proxy's choice of client address
family may not match the server's choice address family. Without
MultiHomed => 1, the proxy may try the wrong address family first,
and give up without trying the other.

This makes use of TLSProxy, which was expanded to use IO::Socket::IP
(which is a core perl module) or IO::Socket::INET6 (which is said to
be more popular) instead IO::Socket::INET if one of them is installed.

CRIME protection: disable compression by default, even if OpenSSL is
compiled with zlib enabled. Applications can still enable compression by
calling SSL_CTX_clear_options(ctx, SSL_OP_NO_COMPRESSION), or by using
the SSL_CONF library to configure compression. SSL_CONF continues to
work as before:
SSL_CONF_cmd(ctx, "Options", "Compression") enables compression.
SSL_CONF_cmd(ctx, "Options", "-Compression") disables compression (now
no-op by default).
The command-line switch has changed from -no_comp to -comp.

TLSProxy was failing if we are Configured with compression because it
doesn't support it. This fix simply switches compression off for the
purposes of the test.

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.

Use a dynamic engine for ossltest engine so that we can build it without
subsequently deploying it during install. We do not want people accidentally

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.
