  Stephan, Martin,

could you check the enclosed patch ? I'm commiting it to SVN head too
but it's probably easier to review that way.

Basically it adds 3 parsing options, and for the old entry points
xmlDump* not xmlSave based it forces the XML_SAVE_AS_XML bypassing
the doc type in case of HTML documents. that should fix Stephan problem
and also provide ways to do things with xmlSave when available.
For the 'problem' of the added meta an XML_SAVE_IMMUTABLE option could
be added that sounds more generic, but i'm not adding this in the patch
to not complicate things.

I hope i didn't miss any old entry point which behaviour was modified in
2.7.1, and not missing places where the new flags should be checked too,

Daniel
