Add public String[] getRawCommandline() to avoid OS dependency code in unit tests

Hi

In order to avoid such bad OS dependency code as below

        String[] commandLine = cl.getCommandline();

        if ( Os.isFamily( Os.FAMILY_WINDOWS ) )
        {
            if ( Os.isFamily( Os.FAMILY_WIN9X ) )
            {
            	assertArrayEquals( new String[] { "command.com", "/C", "\"gcc -Ip1 -Ip2 -Isp1 -Isp2 -o object.o -c source.c\"" },  commandLine );
            }
            else
            {
               	assertArrayEquals( new String[] { "cmd.exe", "/X", "/C", "\"gcc -Ip1 -Ip2 -Isp1 -Isp2 -o object.o -c source.c\"" },  commandLine );
            }
        }
        else
        {
            assertArrayEquals( new String[] { "gcc", "-Ip1", "-Ip2", "-Isp1", "-Isp2", simpleArgv[0], simpleArgv[1],
                    simpleArgv[2], simpleArgv[3] }, commandLine );
        }

this PR introduces the function public String[] getRawCommandline() so that the above code be reformated as

        String[] commandLine = cl.getRawCommandline();
        assertArrayEquals( new String[] { "gcc", "-Ip1", "-Ip2", "-Isp1", "-Isp2", simpleArgv[0], simpleArgv[1],
                    simpleArgv[2], simpleArgv[3] }, commandLine );
