I do not see a pkcert directory in this change?

We should have a test where we use a certificate database based on which we
cannot authorize the request as well. I don't see any handling of that in the
current APIs. Is that ignored in this first changelist?

+  TlsSocket.setCertificateDatabase(testPkcertDatabase.toNativePath());
+  // TODO(3593): Use a Dart HTTPS server for this test using TLS server sockets.
+  var tls = new TlsSocket("www.google.dk", 443);

+  List<String> chunks = <String>[];
+  tls.onConnect = () {

+      "GET / HTTP/1.0\r\nHost: www.google.dk\r\n\r\n".charCodes;
+    tls.writeList(get_list, 0, 20);
+    tls.writeList(get_list, 20, get_list.length - 20);
+  };
+  tls.onData = () {
+    var buffer = new List(2000);
+    int len = tls.readList(buffer, 0, 2000);
+    var received = new String.fromCharCodes(buffer.getRange(0, len));
+    chunks.add(received);
+  };
+  tls.onClosed = () {
+    String fullPage = Strings.concatAll(chunks);
+    print(fullPage);
+    Expect.isTrue(fullPage.contains('</body></html>'));
+    tls.close();
