conf: Don't always recalculate initial memory size from NUMA size totals
When implementing memory hotplug I've opted to recalculate the initial memory size (contents of the <memory> element) as a sum of the sizes of NUMA nodes when NUMA was enabled. This was based on an assumption that qemu did not allow starting when the NUMA node size total didn't equal to the initial memory size. Unfortunately the check was introduced to qemu just lately. This patch uses the new XML parser flag to decide whether it's safe to update the memory size total from the NUMA cell sizes or not. As an additional improvement we now report an error in case when the size of hotplug memory would exceed the total memory size. The rest of the changes assures that the function is called with correct flags.
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.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
