Detected by valgrind. Leaks introduced in commit 4d5383f.
* tools/virsh.c: fix memory leaks on cmdDomXMLFromNative and cmdDomXMLToNative.
* how to reproduce?
% virsh dumpxml ${guest} > foo.xml
% valgrind -v --leak-check=full virsh domxml-from-native qemu-argv foo.xml
% valgrind -v --leak-check=full virsh domxml-to-native qemu-argv foo.xml

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
