[libvirt] [RFC PATCH 3/5] qemu: driver: Remove support for native->XML conversion

[Peter Krempa]

This code is really neglected and does not at all work reliably. It
can't even be used for converting our own commandline back.

Since this was mostly useful for aiding migration from manually run qemu
to libvirt and will not work for this puspose in many cases it's not
worth having in my opinion.
