    Continue working on paragraph base direction.
    Support per-buffer default paragraph direction.
    
     buffer.h (struct buffer): New member paragraph_direction.
     buffer.c (init_buffer_once): Initialize it.
     (syms_of_buffer): Declare Lisp variables
     default-paragraph-direction and paragraph-direction.
     dispextern.h (struct it): New member paragraph_embedding.
     xdisp.c (init_iterator): Initialize it from the buffer's value
     of paragraph-direction.
     <Qright_to_left, Qleft_to_right>: New variables.
     (syms_of_xdisp): Initialize and staticpro them.
     (set_iterator_to_next, next_element_from_buffer): Use the value of
     paragraph_embedding to determine the paragraph direction.
     bidi.c (bidi_line_init): Fix second argument to
     bidi_set_sor_type.
     (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
     (bidi_get_next_char_visually): Record the last character of the
     separator in separator_limit, not the character after that.
     (bidi_find_paragraph_start): Accept character and byte positions
     instead of the whole iterator stricture.  All callers changed.
