* xterm.c: Make symbols static if they're not exported.

(x_raise_frame, x_lower_frame, x_wm_set_window_state):
(x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):
(x_destroy_window, x_delete_display):
Now static.
(x_dispatch_event): Now static if ! (USE_MOTIF || USE_X_TOOLKIT).
(x_mouse_leave): Remove; unused.
* xterm.h (x_display_info_for_name, x_raise_frame, x_lower_frame):
(x_destroy_window, x_wm_set_window_state, x_wm_set_icon_pixmap):
(x_delete_display, x_initialize, x_set_border_pixel, x_screen_planes):
Remove decls.
(x_mouse_leave): Declare only if WINDOWSNT.
(x_dispatch_event): Declare only if USE_MOTIF or USE_X_TOOLKIT.
(xic_create_fontsetname): Declare only if HAVE_X_WINDOWS &&
USE_X_TOOLKIT.
