        * scanner.c (gfc_advance_line): Call debug_hooks->start_source_file

        included files.
        (gfc_define_undef_line): New function.

        preprocessor lines.
        (gfc_parse_file): Call debug_hooks->start_source_file and
        debug_hooks->end_source_file for the main source file if
        requested by the debug format.
