gtk3/gtk/gtkrc.c
Tim Janik 2b2667e791 new function. many functions adapted to use GScanner for scanning. 
* gtk/gtkrc.h (gtk_rc_parse_string): new function.
        * gtk/gtkrc.c: many functions adapted to use GScanner for scanning.
        (gtk_rc_parse): use gtk_rc_parse_any for parsing.
        (gtk_rc_parse_string): new function to support parsing from
        strings, just calls gtk_rc_parse_any.
        (gtk_rc_parse_any): new function using GScanner as lexer.
