new file for GScanner: Flexible lexical scanner for general purpose. added

* gscanner.c: new file for GScanner: Flexible lexical scanner for
        general purpose.
        * glib_pre2.h: added GScanner includes. added g_strconcat and g_strtod.
        gutils.c (g_strconcat): new function for string concatenation of NULL
        terminated parameter list.
        (g_strtod): new function to perform best string to double conversion
        with or without consideration of the current locale.
