* utils.c: (warning) added call to warning_hook

        * source.c: (find_source_lines) modified to call warning in case
        of source vs. executable time stamp mismatch. Simplified object
        file check. Initialized mtime to 0.

        * defs.h: added warning_hook prototype

        * top.c: added warning_hook prototype.

        * gdbtk.c: (perror_with_name_wrapper) new function to call
        perror_with_name safely.
        (gdb_loadfile) added source vs. executable time stamp check.
        (gdbtk_warning) new function to pass a warning message to the gui.
        (gdbtk_ignorable_warning) new function to pass a warning
        to the gui. Used only for the src. vs. exec check.
        (gdbtk_init) added warning_hook
        added include <sys/stat.h>
