tls: honorCipherOrder should not degrade defaults

Specifying honorCipherOrder should not change the SSLv2/SSLv3 defaults
for a TLS server.

Use secureOptions logic in both lib/tls.js and lib/crypto.js
tls: enforce secureOptions on incoming clients

Reuse the secureProtocol and secureOptions of the server when creating
the secure context for incoming clients.
tests: add TLS tests matrix

Add a test that goes through the whole matrix of:
- command line options (--enable-ssl*)
- secureOptions
- secureProtocols

and makes sure that compatible test setups actually work as expected.

The test works by spawning two processes for each test case: one client
and one server. The test passes if a SSL/TLS connection from the client
to the server is successful and the test case was supposed to pass, or
if the connection couldn't be established and the test case was supposed
to fail.

The test is currently located in the directory 'test/external' because
it has external dependencies.
