qemu: Move qemuDomainAttachDeviceLive() into qemu_hotplug.c
There is no good reason for qemuDomainAttachDeviceLive() to live in (ever growing) qemu_driver.c while we have qemu_hotplug.c which already contains the rest of hotplug code. Move the function to its new home. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Kristina Hanicova <khanicov@redhat.com>
