#6 XML validation context not initialized enough

[Miloslav Trmac]

Attached patch fixes an uninitialized memory reference
within libxml
caused by using not-quite-initialized XML validation
context.
It would look more OO to use xmlNewValidCtxt () and
xmlFreeValidCtx (), but the only real change would be using
malloc ()/free () instead of stack allocation;
xmlNewValidCtxt ()
is just malloc () and memset (, 0, ).
