     src/bidi.c (bidi_paragraph_info): Delete unused struct.
     (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
     (bidi_cache_start): New variable.
     (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
     to zero.
     (bidi_cache_fetch_state, bidi_cache_search)
     (bidi_cache_find_level_change, bidi_cache_iterator_state)
     (bidi_cache_find, bidi_peek_at_next_level)
     (bidi_level_of_next_char, bidi_find_other_level_edge)
     (bidi_move_to_visually_next): Compare cache index with
     bidi_cache_start rather than with zero.
     (bidi_fetch_char): Accept new argument STRING; all callers
     changed.  Support iteration over a string.
     (bidi_paragraph_init, bidi_resolve_explicit_1)
     (bidi_resolve_explicit, bidi_resolve_weak)
     (bidi_level_of_next_char, bidi_move_to_visually_next): Support
     iteration over a string.
     (bidi_set_sor_type, bidi_resolve_explicit_1)
     (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
     can now be zero (for strings); special values 0 and -1 were
     changed to -1 and -2, respectively.
     (bidi_char_at_pos): New function.
     (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
     Call it instead of FETCH_MULTIBYTE_CHAR.
     (bidi_move_to_visually_next): Abort if charpos or bytepos were not
     initialized to valid values.
     (bidi_init_it): Don't initialize charpos and bytepos with invalid
     values.
     src/xdisp.c (compute_display_string_pos)
     (compute_display_string_end): Accept additional argument STRING.
     (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
     (reseat_to_string): Initialize bidi_it->string.s and
     bidi_it->string.schars.
     src/dispextern.h (struct bidi_string_data): New structure.
     (struct bidi_it): New member `string'.  Make flag members be 1-bit
     fields, and put them last in the struct.
     (compute_display_string_pos, compute_display_string_end): Update
     prototypes.
