[libvirt] [PATCH 05/14] Use a libvirt custom struct for virURIPtr

From: "Daniel P. Berrange" <berrange at redhat.com>
Instead of just typedef'ing the xmlURIPtr struct for virURIPtr,
use a custom libvirt struct. This allows us to fix various
problems with libxml2. This initially just fixes the query vs
query_raw handling problems.
