On X, always make pointer visible when deleting frame (Bug#17609).

* frame.c (frame_make_pointer_visible, frame_make_pointer_invisible):
Pass frame as arg.
* frame.h (frame_make_pointer_visible, frame_make_pointer_invisible):
Adjust prototypes.
* cmds.c (Fself_insert_command): Use SELECTED_FRAME.
* keyboard.c (gobble_input): If there is no terminal input error,
make sure the pointer is visible for all frames on this terminal.
* xterm.c (x_free_frame_resources): Always enable pointer visibility.
