Remove unnecessary casts.

* xterm.c (x_term_init):
* xfns.c (x_set_border_pixel):
* widget.c (create_frame_gcs): Remove casts to unsigned long etc.
These aren't needed now that we assume ANSI C.

        * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
        It's more likely to cause problems (due to unsigned overflow)
        than to cure them.
