SF #989185: Drop unicode.iswide() and unicode.width() and add

unicodedata.east_asian_width().  You can still implement your own
simple width() function using it like this:
    def width(u):
        w = 0
        for c in unicodedata.normalize('NFC', u):
            cwidth = unicodedata.east_asian_width(c)
            if cwidth in ('W', 'F'): w += 2
            else: w += 1
        return w
