        Fixes for signed/unsigned in PangoAttrIterator ((#166700,
        Morten Welinder)

        * pango/pango-attributes.c (pango_attr_iterator_range):
        Clamp results to G_MAXINT to avoid negative numbers from
        signed/unsigned conversions.

        * pango/pango-attributes.c: Make PangoAttrIterator
        start_index/end_index unsigned to match PangoAttribute.
        Change various local variables to match.

        * pango/ellipsize.c (advance_iterator_to)
        pango/pango-attributes.c (pango_attr_iterator_range)
        pango/pango-glyph-item.c (pango_glyph_item_apply_attrs)
        pango/pango-layout.c (pango_layout_line_get_empty_extents):
        Always check the return value from pango_attr_iterator()
        to deal with potential infinite loops when trying to
        advance to position G_MAXINT.

        * pango/pango-layout.c (pango_layout_set_text): Handle
        the case where the text passed in is longer than
        than G_MAXINT and length < 0.

        * pango/pango-attributes.c (pango_attr_list_splice): Be
        careful about integer overflow - clamp addition.
