[Libreoffice] [PATCH] De-Java-ise flat XML export

[Peter Jentsch]

Hi Jan, 

I'm attaching a patch I somehow managed to patiently pull out of git :-)

As I'm new to C++, libxslt, git and a few other things involved in
creating the patch I feel it must be full of warts and cause random
crashes, but it seems to work and might be useful anyway.

Basically, the patch provides an alternative service implementation
to be used by XSLTFilter.cxx. Use of the libxslt implementation can be
triggered by adding "libxslt" as second parameter to the "UserData"
configuration of an xslt filter. This second parameter is currently
unused for xslt filters. 

To completely remove the java dependency for xslt filters, the
xsltvalidation service would also need to be replaced by an
implementation based on libxslt. 

Also, the Office 2003 XML export filters use a saxon extension
implemented in Java, which needs to be replaced by a libxslt extension
if Office 2003 XML export should be supported without Java, too. 

The flat xml export could be implemented as a pure C++ xml Filter
indendendently of the xslt filter, as proposed in the SDK examples, I
suppose, and I'd like to do that next. 

I personally like the idea to make the implementation to use
configurable, instead of completely removing the Java based xslt filter
implementation. 

Cheers, 

Peter
