        Implements a port blocking black list that matches Firefox's

        The layout test attempts to load an image at an invalid domain name on each
        of the black listed ports.  Using dumpResourceLoadCallbacks(), DRT is able
        to see the error codes for each resource.  A successful test shows the blocked
        error for each image load except for the few that are standard or should
        succeed due to exemptions.

        * security/block-test-expected.txt: Added.
        * security/block-test.html: Added.
