* xterm.c (x_wm_hints): New variable.
(x_wm_set_window_state, x_wm_set_icon_pixmap, x_wm_set_icon_position): Use x_wm_hints. (x_term_init): Set the `input' field of x_wm_hints, and its flag. * xterm.c (x_text_icon): Call x_wm_set_icon_pixmap with a pixmap of zero, to clear the pixmap. (x_wm_set_icon_pixmap): Accept this protocol; if pixmap is zero, specify no pixmap for the icon. * xterm.c (x_set_window_size): Call check_frame_size to make sure that the requested dimensions are within acceptable limits. Store the new size information in the frame structure. * xterm.c (x_wm_set_size_hint): Don't try to set the base_height and base_width elements of size_hints if PBaseSize is not #defined. Set the minimum frame size according to the information returned by check_frame_size. * xterm.c (XTread_socket, x_do_pending_expose): Call change_frame_size with a DELAY of 1. * xterm.c (in_display): Deleted this; it's never used in xterm.c, and there is another variable by the same name in dispnew.c. * xterm.c (FRAME_IS_TERMCAP, FRAME_IS_X, FRAME_HAS_MINIBUF): Renamed these to FRAME_TERMCAP_P, FRAME_X_P, and FRAME_HAS_MINIBUF_P, for consistency with the rest of the frame macros.
