[xslt] Changes of internal structures

["Kasimier Buchcik" <k buchcik 4commerce de>]

Hi,

In the course of refactoring the internals of Libxslt we will change the
struct _xsltStylePreComp (xsltInternals.h) in the near future. The plan
is
to have specialized structures for each of the xslt instructions to hold
precompiled data.
Note that xsltInternals.h is not part of the API/ABI.

Regards,

Kasimier
