        nrwt - clean up create_driver interface and print out the
        command line used for DumpRenderTree/TestShell.

        This patch adds a driver_cmd_line() call to the Port class in
        order to retrive the command line to print it out (as part of
        --print config).

        In addition, this patch cleans up the Port.create_driver()
        signature and the Driver constructor interface to take a worker
        number and no longer require the image_path argument (Chromium's
        drivers now synthesize the image_path from the worker number
        internally).
