So far, Libvirt configures memory-backend-* for memory hotplug, possibly NUMA nodes and in a few other cases. This patch switches to constructing the memory-backend-* command line for all cases. To keep ability to migrate guests a little hack is used: the ID of the object is set to the one that QEMU uses internally anyways. These IDs are stable (first started to appear somewhere around v0.13.0-rc0~96) and can't change. In fact, this patch does exactly what QEMU does internally. The reason for moving the logic into Libvirt is that QEMU wants to deprecate the old style of specifying memory. So far, only x84_64 test cases are changed, because tests for other architectures use older capabilities, which still lack the QEMU_CAPS_MACHINE_MEMORY_BACKEND capability and they don't report the RAM ID.
