Fix crash with bidi display on the last empty line (bug#6030).

 xdisp.c (display_line): Don't assume 2nd call to
 get_next_display_element cannot return zero.  (Bug#6030)

Move code that bidi-iterates out of display property to a separate function.

 xdisp.c (iterate_out_of_display_property): New function, body from pop_it.
 (pop_it): Use it.
