* Scripts/cvs-create-patch: Added code to handle getting changes in the top-level
        directory passed in.

        * Scripts/webkitdirs.pm: Eliminate use of changing the current directory and using
        getcwd() in the code to find the base product dir. Added code to handle unusual
        base product directory values that use SRCROOT.
