Fix encoding of PDF document metadata in output of pdftohtml

pdftohtml simply copies the PDF document title into the <title> HTML
tag, which fails when the title is UCS-2 encoded, or if it contains
characters which are in pdfDocEncoding (a ISO 8859-1 superset), but not
in ISO 8859-1.  This patch fixes the problem by decoding UCS-2 or
pdfDocEncoding into Unicode, then encoding this in the desired output
encoding.  HTML escaping wasn't being done either, so I have used the
existing function HtmlFont::HtmlFilter to perform both HTML escaping
and character set encoding. This static method had to be made public
to call it from pdftohtml. See bug #37900.
