Changeset 747a9c4 in mod_gnutls for test/tests/05_client_handshake_error

Create a new test for handling client-side handshake errors

Prior to f363569cf5563271019bfb439980c7ad08e5ac30 the test
09_verify_no_sni_fails_with_wrong_order expected the client to reject
the presented certificate. This is rather imprecise for vhost
selection testing, but did exercise an otherwise untested code path:
What happens if the client cancels the handshake?

This commit adds a new test explicitly covering that situation.
