        (g_vsprintf): removed this function which was not publically
        exported in glib.h. to export it, it should have been named
        differently in the first place, since its semantics differ from
        vsprintf(). apart from that, it was a possible cause for
        problems since it worked on a previously allocated memory area and
        was used in a lot places of glib. exporting it would have been a
        guararant for problems with threaded programs.
        (g_printf_string_upper_bound): exported this function to return
        a string size, guarranteed to be big enough to hold the fully
        expanded format+args string. added 'q', 'L' and 'll' flag handling.
        in fact, the newly allocated area is in most cases much bigger than
        required.
