default-paragraph-direction and paragraph-direction.

of paragraph-direction.
<Qright_to_left, Qleft_to_right>: New variables.

(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.
Start of work on bidi Emacs 23/24.
bidi.c (bidi_initialize): Fix initialization of bidi_type_table.
xdisp.c (set_iterator_to_next): Fix position setting after call
to bidi_get_next_char_visually.

commentary. Add Copyright blurb.
* lisp.h (USE_2_TAGS_FOR_INTS): New macro.
(LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P): New macros.
(enum Lisp_Type): Use them. Give explicit values.
(Lisp_Type_Limit): Remove.
(XINT, XUINT, make_number) [!USE_LISP_UNION_TYPE]:
(MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
Pay attention to USE_2_TAGS_FOR_INTS.
