    Discovery of replacing display properties now uses the same code · fc6f18ce

    as the display engine.  Tested OK with display properties whose
    value is a list.
    
     src/dispextern.h (struct bidi_it): New member frame_window_p.
     (bidi_init_it, compute_display_string_pos): Update prototypes.
     src/bidi.c (bidi_fetch_char): Accept additional argument
     FRAME_WINDOW_P and pass it to compute_display_string_pos.  All
     callers changed.
     (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
     it to initialize the frame_window_p member of struct bidi_it.
     src/xdisp.c (handle_display_spec): New function, refactored from the
     last portion of handle_display_prop.
     (compute_display_string_pos): Accept additional argument
     FRAME_WINDOW_P.  Call handle_display_spec to determine whether the
     value of a `display' property is a "replacing spec".
     (handle_single_display_spec): Accept 2 additional arguments BUFPOS
     and FRAME_WINDOW_P.  If IT is NULL, don't set up the iterator from
     the display property, but just return a value indicating whether
     the display property will replace the characters it covers.
     (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
     frame_window_p members of struct bidi_it.
