* xterm.c (x_wm_hints): Variable deleted.  This has to be
	per-screen.  Duh.
	* xterm.c (x_wm_set_window_state, x_wm_set_icon_pixmap,
	x_wm_set_icon_position): Use F->display.x->wm_hints, rather than
	x_wm_hints.
	(x_term_init): Don't initialize x_wm_hints here.
	* xterm.c (x_set_text_property): Properly balance the BLOCK_INPUTs
	and UNBLOCK_INPUTs.  And remember that VALUE is the strin we want
	to set the name to, not PROPERTY.

	* xterm.c (x_set_text_property): Define this appropriately for
	X11R3 and X11R4.

	* xterm.c (x_set_text_property): Make this take a Lisp_Object
	string as an argument, rather than a pointer and a length.

	* xterm.c: Doc fixes.

	* xterm.c [USG5]: Don't include <sys/types.h>.

	* xterm.c (x_make_frame_invisible): Instead of calling XWithdraw
	window, which isn't widely available, write out what it does,
	since that's not much.
	(x_iconify_frame): Explicitly perform both the X11R3 and X11R4
	methods for iconification; don't use XIconifyWindow, since that's
	not present in R3.

	* xterm.c (x_wm_set_size_hint): Don't bother setting the
	base_width and base_height members; their function is performed
	just as well by the min_width and min_height members, and if we
	use XSetNormalHints instead of XSetWMNormalHints, we can be
	compatible with R3.

	* xterm.c (x_error_handler): There is no way to invoke the default
	error handler which works on all versions of X11, so don't bother;
	call XGetErrorText and print the message ourselves.

	* xterm.c (x_term_init): Don't use MAXHOSTNAMELEN; this isn't
	defined on all systems.  Since we only use that as an initial
	guess anyway, it's not very important.

	* xterm.c (x_set_text_property): New function.
