XMLSec/LibXML interop update

Hi, Joseph!

Please update interop information for XMLSec/LibXML as follows:

    Canonicalization:

        * Y1: October 11 examples
          <http://lists.w3.org/Archives/Public/w3c-ietf-xmldsig/2000OctDec/0059.html>

    Exclusive Canonicalization:

        * Y1: merlin-1
          <http://lists.w3.org/Archives/Public/w3c-ietf-xmldsig/2002JanMar/att-0032/01-merlin-exc-c14n-one.tgz>

        * Y3: 01-merlin-iaikTests-two.tar.gz
          <http://lists.w3.org/Archives/Public/w3c-ietf-xmldsig/2002AprJun/att-0056/01-merlin-iaikTests-two.tar.gz>

        * Y4: merlin-c14n-three.tar.gz
          <http://lists.w3.org/Archives/Public/w3c-ietf-xmldsig/2002AprJun/att-0228/01-merlin-c14n-three.tar.gz>

    XPath 2 Filter:

        * Y1:  merlin-xpath-filter2-three.tar.gz
          <http://lists.w3.org/Archives/Public/w3c-ietf-xmldsig/2002AprJun/att-0306/02-merlin-xpath-filter2-three.tar.gz>

        * on ~860 bogomips box (Celeron 400) the XPath 2 transform
          alone is done in about 120-150 msec; the whole file
          signature/verification takes about 800-850 msec (the combination
          of enveloped transform + XPath 2 filter is not optimized yet)
