Retrospective commit from 2009-12-26.
Redesign handle_stop_backwards.
Fix character mirroring for non-ASCII characters.
xdisp.c (handle_stop_backwards): Call compute_stop_pos in the
loop, instead of calling handle_stop. Call handle_stop only once,
after the loop.
(next_element_from_buffer): Don't call handle_stop_backwards if at
stop position. If base_level_stop is zero, set it to 1.
term.c (append_glyph): Fill resolved_level and bidi_type slots
of struct glyph for unidirectional display.
xdisp.c (set_cursor_from_row): Handle zero-width characters.
bidi.c (bidi_mirror_char): More efficient code (suggested by
Ehud Karni <ehud@unix.mvs.co.il>). Don't even try to mirror
non-ASCII characters.
