Set up the bidi iterator for iterating display strings and overlay strings.
Not tested yet, just compiled.
src/xdisp.c (handle_single_display_spec, next_overlay_string)
(get_overlay_strings_1, push_display_prop): Set up the bidi
iterator for displaying display or overlay strings.
(forward_to_next_line_start): Don't use the shortcut if
bidi-iterating.
(back_to_previous_visible_line_start): If handle_display_prop
pushed the iterator stack, restore the internal state of the bidi
iterator by calling bidi_pop_it same number of times.
(reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
and we are bidi-iterating, don't decrement the iterator position;
instead, set the first_elt flag in the bidi iterator, to produce
the same effect.
(reseat_1): Remove redundant setting of string_from_display_prop_p.
(push_display_prop): xassert that we are iterating a buffer.
(push_it, pop_it): Save and restore the state of the
bidi iterator. Save and restore the bidi_p flag.
(pop_it): Iterate out of display property for string iteration as
well.
(iterate_out_of_display_property): Support iteration over strings.
(handle_single_display_spec): Set up it->bidi_it for iteration
over a display string, and call bidi_init_it.
src/bidi.c (bidi_cache_start_stack, bidi_push_it): Use IT_STACK_SIZE.
src/dispextern.h (struct iterator_stack_entry): New member bidi_p.
(struct it): Member bidi_p is now a bit field 1 bit wide.
