Peter Krempa 50ce3463d5 qemu: hotplug: Remove legacy quirk for 'dimm' address generation 
Commit b7798a07f9 (in fall of 2016) changed the way we generate aliases
for 'dimm' memory devices as the alias itself is part of the migration
stream section naming and thus must be treated as ABI.

The code added compatibility layer for VMs with memory hotplug started
with the old scheme to prevent from generating wrong aliases. The
compatibility layer broke though later when 'nvdimm' and 'pmem' devices
were introduced as it wrongly detected them as old configuration.

Now rather than attempting to fix the legacy compat layer to treat other
devices properly we'll be better off simply removing it as it's
extremely unlikely that somebody has a VM started in 2016 running with
today's libvirt and attempts to hotplug more memory.

This fixes a corner case when a user hot-adds a 'dimm' into a VM with a
'dimm' and a 'nvdimm' after restart of libvirtd and then attempts to
migrate the VM.

Libvirt API for virtualization

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.

For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
