Subject: [PATCH] (separate_textual_runs): Use <const Charc *> instead of
 <const Emchar *>. (x_text_width): Likewise.
 (x_output_display_block): Use <Charc_dynarr *> instead
 <Emchar_dynarr *>; modify for <structure rune> change.
 (x_output_string): Use <Charc_dynarr *> instead of
 <Emchar_dynarr *>.
