* poppler/UGooString.h: Patch by Krzysztof Kowalczyk <kkowalczyk@gmail.com> to improve performance. See bug 7808 for details.

        * glib/poppler-document.cc (info_dict_get_string): Refactor
        _popper_goo_string_to_utf8() out into it's own function.

        * glib/poppler-page.cc (poppler_page_get_property): Use
        _popper_goo_string_to_utf8() here to convert ucs2 page labels.

        * glib/poppler-page.cc (poppler_page_get_selection_region): Add
        braces to fix warning.

        * poppler/PageLabelInfo.cc: If the label prefix string has a ucs2
        marker, append the number part of the label as ucs2 (#5952).

martink's work (7-xpdf-3.01-goo-improvements.patch), with some tweaking
by me.
