[xml] Release of libvirt-2.9.3

  This is a security release, I didn't tried to push a number of other
patches considering urgency.

  That release is dedicated to the memory of Bill Brack who was my
co-maintainer for many years on libxml2 and libxslt, we became friends,
he has a huge influence still on way I do things. Unfortunately he passed
away last February. I'm sure he would have commented that celebrating
his legacy with a release with so many CVE would be a tribute to his
programming skills, because he always approached life with a sense of
humor. RIP Bill, the code still lives but OpenSource is more about
people than code !

  So yes that release is packed with Security and ugly bugs fixes,
more than overall improvements, I have put signed tarballs and rpms
to the usual place at
