TLSProxy starts s_server and specifies the number of client connects
it should expect. After that s_server is supposed to close down
automatically. However, if another test is then run then TLSProxy
will start a new instance of s_server. If the previous instance
hasn't closed down yet then the new instance can fail to bind to
the socket.

Because we're requiring Perl 5.10.0 and the 'parent' didn't appear
before Perl 5.10.1, we need to resort to the older parent module
declaration style, modifying @ISA.

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.

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.

If the client sends a status_request extension in the ClientHello
and the server responds with a status_request extension in the
ServerHello then normally the server will also later send a
CertificateStatus message. However this message is *optional* even
if the extensions were sent. This adds a test to ensure that if
the extensions are sent then we can still omit the message.

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.

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.
