* libxslt/transform.c: As suggested by Bill, I changed
  xsltShallowCopyNsNode() to return an xmlNsPtr instead of
  an int. The fix of bug #350085 is OK; i.e. the removal
  of the call to xsltFreeRVTs() in
  xsltApplyStylesheetInternal(). I think I tried to clear
  the transformation context as much as possible, in case
  it is reused; Daniel informed me on the list that reusing
  the context is not intended, so no need anymore to try
  to free the fragments immediately after the transformation.
