Separate xetex-inputenc test sample in working and non-working parts.
Sort HTML-only tests.
Update tagging and ignore-rules.
Change inputencoding to utf8 in dedicated tests (get pdf4_texF working).
A \clearpage command issued right before \end{CJK} is recommended by the
package author to prevent any un-processed CJK chars outside the
\begin{CJK} and \end{CJK} scope. Otherwise, TOC, header, footer,
and may contain CJK chars but get processed outside the CJK environment scope.
Tha new dedicated export test fails without the fix.
