Add a standard string api strncat_s() to replace merge_cmdline() to make code more readable. Another change is that the multiboot cmdline will be appended to the end of configured SOS bootargs instead of the beginning, this would enable a feature that some kernel cmdline paramter items could be overriden by multiboot cmdline since the later one would win if same parameters configured in kernel cmdline.
